From electronic scrap to pure gold

RECYCLING EXCLUSION OF IMPLIED FROM WASTE MATERIAL, AND THEIR TREATMENT for reuse in production processes. The process involves the following operations: WASTE COLLECTION, EXTRACTION 'separation' MATERIALS PROCESSING AND FINALLY making new products from recycled materials.

An interesting item in the process of recycling is that when recycling electronic - electronic waste in most cases as a product can get pure gold, silver, and other valuable and precious metals.

Commonly recycled waste to obtain gold are personal computers, cell phones, various audio and video equipment, TV equipment and the like.

The production process of the listed electronic devices it is necessary to use gold. Because of the price that gold holds, the process of production strictly and precisely involves only small quantities of these precious and valuable metals. However, they are almost always present and interesting because of its value to companies for recycling.

If you are skilled enough you can also start the process of collecting and recycling of gold. However, if it is still classified into the category of people who are not able to recycle gold yourself then you are left with the other, no less valuable option to collect waste containing gold and continue to sell a company that operates in the domain.

Gold is currently stable 'currency' for trading on world stock markets. Excellent holding cost, which is substantially increasing. Due to its characteristics Gold is always in demand, and how the process of digging gold from the mines quite expensive and difficult business buying recycled gold is a growing phenomenon worldwide.

Where and how to find gold in electronic devices?

The answer to the question above, look for the link.

On the day, you can also link to find content related to the topic of recycling the gold points, or learn something about getting a pure gold and selling the same.

If you carefully read the articles you will see that the process of recycling solid gold dangerous and should be approached with great caution. Involves working with dangerous acids, and leading a team to ensure appropriate working environment and work equipment.

However, if you are not familiar with this type of work is repeated again, you can easily collect pieces that contain gold and sell them at a fairly good price.

How much gold can be found in electronic waste?

According to some calculations, one ton of old mobile phone contains about 15,000 U.S. dollars worth of metals. This figure shows how to be profitable in the process of recycling old electronic equipment, and in addition to these through and keeps the planet earth.

In addition to mobile phones, personal computers are a great source of income in gold and silver. Also in every electronic device we can find plastic, copper, aluminum, glass and similar materials worth recycling.

Tons of electronic waste is worth $ 15,000?

Cellphones for recycling?

According to some sources in Croatia 'applies to the neighboring countries' on a year by collecting 4 kilograms of electric and electronic waste per inhabitant. The average for the EU is 14 pounds of waste per capita, but what is interesting is that in Croatia and neighboring countries outside the EU that waste almost never recycled.

Awareness of collecting electronic waste, environment and large energy savings in our country is still in a difficult level. However, if we imagine a bit and re-read the title of this post we can see that the laziness and carelessness of our planet can cost thousands of dollars, the kuna, euro or marks ... whichever one year or less.

In addition to recycling electronic waste to obtain gold there are many other materials that make cash contributions and failing unless validly tendered and eventually recycled.

The same reports indicate that in Croatia for a year or imported in it produced 73,000 tons of electronic devices, while the recorded collection of waste from these devices on an annual basis until 5700 tons.

Roughly counting, according to statistical data available, in Croatia a year properly disposed of only 1.29 pounds of electronic waste per inhabitant, which is less than half of the 'de-committed' waste per capita per year.

A bunch of money to waste ...

Collection and recycling of electronic and electronic equipment can be a very lucrative business. In fact, tons of discarded used cell phones 'about 6,000' contains 3.5 kg of silver, 340 grams of gold, 140 grams of palladium and 130 kg of copper.

Experts who deal with the problem of electronic waste disposal calculated that one ton of electrical and electronic waste contains over 15,000 U.S. dollars worth of metals. Elements such as plastic, glass and similar are not taken into account, even though they are recyclable.

GOLD, SILVER, COPPER - CASH

How to extract gold from cell phones?

How to recycle gold from processors?

FOR EXAMPLE WITH GOLD RECYCLING PROCESS WILL TAKE OLD 'BLACK' PROCESSOR WITH BODY OF FIBER THAT WILL INCLUDE GOLD mostly just on pins BELOW. GIVE pins that contact between the processor and motherboard are gilded OR Electroplated gold.

To recycle gold, the first thing we need to do is remove the pins from the body gilt processors. The processor does not contain valuable elements and it is important to remove the pins from it for further processing.
If you want to be with a detailed processor and remove the ceramic capacitors that contain palladium.
Pins can remove the burner, some tools like pliers or the easiest method, hot air.
Watch the video to remove the gold pins with CPU hot air?
Pins to collect and prepare for recycling. Golden glow that you see on the pins is actually a thin layer of gold on them. It is a value we want to get away from waste.

Recycling gold from computer. How?

We all know that recycling is good for the preservation of our planet and our environment. Glass, plastic, paper and similar materials that are recyclable are quite REQUESTED JUST BECAUSE. The process listed RECYCLING MATERIAL is far cheaper, more efficient and by nature less harmful than the production process.

Economically recyclable materials is a very lucrative business. The main reason, the initiator of the whole story about recycling, as always, money. If the story reintroduced with money and gold then it becomes even more interesting.

As the title suggests, in this article we will look at the recycling of gold from a personal computer. Specifically, computers, as well as other electronics mali real mine of gold, silver, copper, aluminum and other precious, precious and other metals. In addition to metals in the process of recycling of electronics and computers can draw a lot of plastic, glass, fiber and other similar materials.

However, gold is currently most in recycling processes, and this because of their value almost linearly with each passing moment goes up.

The price of gold in the last five years has risen dramatically, according to diagrams that are given to find everywhere in the stock markets and internet sites the odds are that gold will continue to rise.

All this leads to the fact that people want as much as possible to have the gold, if not that then at least to invest in gold.

The process of recycling gold is not rocket science, but still it's not so innocuous procedure. Specifically, during the recycling process is necessary to use the acids that are very dangerous to human health and the environment. Depending on the procedure for the acid to be used may be more or less dangerous. In any case, if you want to try your hand at gold recycling is necessary to strictly observe the safety precautions related to the handling of hazardous acids.

More info about the collection of waste for recycling, separation, and recycling of gold you can just read the link. However, the website was done in English, but the ex-YU languages ​​does more quality content on this topic.

Before you decide to recycle scrap gold to obtain a thorough inspection process and the way that is handled with acids.

Also, it is important when collecting waste the opportunity to know what the yield of gold each piece can give. Does not contain every electronic device in the gold itself.

Familiarize yourself with the details related to recycling, extraction of gold, weighing and evaluation of gold pieces. On the web site you can also find all the karats, weight and purity of gold alloys. How test gold and what is the difference between gold and gold pieces.

Gold from garbage, recycling electronics

GARBAGE OR ELECTRONIC WASTE HAS BECOME A REAL SOURCE OF RECYCLING AND EXTRACTION OF PRECIOUS METALS FROM HIM. CERTAIN PROCESS OF ELECTRONICS IS NECESSARY to use certain amounts of gold, silver and other precious metals. BECAUSE IT IS WHEN shed old and outdated ELECTRONICS RECYCLING turning to precious metals from it.

Suffice it easier to recycle electronics and get the gold, but ga digging in the mines. Digging gold ore in the old fashioned way in the mines is quite environmentally acceptable, economically viable if we compare this process with recycling electronics.
Recycling gold is a lucrative and very profitable business.
Find your part in this process. Collection, separation, recycling, sale of gold and so the circle. Surely if you are skilled, you can find your place in the chain profits. If not for that kind of job you might want to invest in a business with gold.
Read a little more about how to invest in gold and not to buy.

How to melt gold?

WHEN RECYCLING gold, or gold ore excavating ore te essential process in gold is chemically dissolve the gold. You should know that gold is rare metal, precious and highly valued. In obtaining gold from ore require considerable amounts of raw materials. FOR ONE GRAM PURE GOLD NEED MORE TONS excavated ore from which it gets the gold.

To extract gold from raw materials and get the required purity of the gold pieces you need to use a chemical process. Because of its features gold is very durable metal, among other difficult soluble, antikorozivan and excellent conductor. To extract gold from raw material processing needed to use the well known method of melting gold using acid 'aqua regia' or translated Aqua regia.

Aqua regia word itself tells us what kind of fluid it is. Specifically aqua regia is one of the few acids 'acid blend' that can dissolve the gold. Aqua regia is essentially a combination of the two acids, none of which can dissolve gold independently - without the operation of the other acid.

If you try to dissolve gold in hydrochloric acid, the reaction with the gold would not see anything. To get the reaction we want to add more hydrochloric acid and nitric acid. We now have a blend of 'aqua regia' with us known as aqua regia, which oxidizes the gold and build a chemical compound HAuCl4.

If you have a gold piece immersed in a certain amount of aqua regia acid reaction can be seen with the gold. Specifically, for a time the gold will melt and 'disappear' into the liquid. Extracting gold from the liquid that has a chemical composition of HAuCl4 is a process that actually get 99% pure gold powder. Extracting gold atom from aqua regia is done using metabisulphite powder, and exactly how the process looks to see the video. On this link is shown in detail process of separating the gold from aqua regia.

Treatment process, separation of gold from impurities can be done in case you are involved in recycling gold. If you have any recyclable waste, such as gold coated metal conductors and the like, using zaltotopke extract and produce gold in ga purity 99% and more.

Working with acids is dangerous so be careful and know how to use them. You should stick to the precautions and have proper protective clothing. Place of work needs to be equipped to deal with hazardous chemicals.

Electrolysis or Miller's procedure for obtaining gold?

Electrolytic refining is one of the most popular procedures for obtaining gold.

Purest gold is obtained by electrolysis 'Wohlwillovim' procedure. Simple electrolytic cell as glass or porcelain bowl. Anodes are contaminated at least 950 fineness of gold, weighing 12 kg and measures 280x230x12 mm and the cathode of a rolled gold plate 999.9 fineness and measures 300x75x0, 25mm.

The cell is filled with electrolyte solution, which contains per liter 50 to 100 g of gold in the form of ions (AuCl4), and an equal weight of hydrochloric acid. Electrolyte temperature should be maintained at 60-70C. Gold dissolves from the anode as a translator in the ion (AlCl4), and the cathode is deposited as a metal:

Anode, Au +4 Cl-(AuCl4) - +3 e (3)
Cathode (AuCl4) - +4 +3 e Au-Cl (4)

Hydrochloric acid plays in dissolving anode. When the electrolyte solution would not have been acidified, the anode should be pulled chlorine.

Electric potential between the electrodes is up to 2V, and the current density up to 1900 A/m2. Such a large current density prevents a large amount of gold clusters in solution electrolytes during refining. At such a high current density cathode is tough, but very compact. Anodes are cast thinner at the lower end and at the edges, to be able to use and to take as long as possible, but it is interrupted when the electrolysis is about 90% of the anode material is melted. To prevent silver chloride anode polarization occurring at the anode dissolution and reaction of silver with hydrochloric acid (occurs only if the proportion of silver in the metallic anode 5% and higher), the electrodes are sometimes connected to a pulsating direct current.

As the gold is deposited on the anode from the cathode, while the silver and other metals electrolytically just melt away, eventually the concentration of gold in solution is greatly reduced. In order to compensate for this loss, it added highly concentrated electrolyte solution of gold (III) chloride or completely replace the electrolyte. Replacing electrolytes is applied when the gold contains platinum metals, electrolysis is performed as long as the concentration of platinum and palladium in the electrolyte has increased to 60 g/dm3.

Along with some gold iridium, osmium and ruthenium can be found in the mud of silver chloride is deposited near the anode. These metals and gold due to sludge mechanical ripping the anode. After treatment with zinc chloride of silver plus a small amount of sulfuric acid, which produces zinc chloride and metallic silver, minted silver will contain gold, and what can be gained from the anode mud of the silver refinery.

Cathodes made of pure gold is removed from the cell for refining every 48 hours, wash up, smelted in an induction furnace and cast into ingots. Of so refined gold 10% is used for designing new cathode and back again in the process.

Electrolytically refined gold has a very high purity (average share of gold from 99.95 to 99.98%). With this the proceedings, although they get less pure gold, are preferred over electrolytic because it takes less time. Miller refining process was completed in one day, and the days of electrolysis gold reserves at the refinery, and he also slows circulation and sales. Although electrolysis obtained gold fineness of 999.9 may be used for monetary purposes, it is mainly used in industry and science. To obtain greater fineness of gold is not enough to simply electrolytic or chemical refining. Consecutive electrolysis can produce gold fineness 999.99, 999.999 and finesse only viable extraction solvents and zone melting.

Most refineries in the world produces gold fineness of 996, while Russian fineness 999th The degree of purity of gold is sufficient for casting in gold bullion held as monetary backing. Small gold bars of a commercially available gold are heavy 12.5 kg and shapes are small bricks. Surface gold bullion offered for sale must be flawless, no cracks, breaks or scratches. Molten gold, temperature, slightly more than the melting point, the left into molds which are coated on the inside with a thin layer of soot. When we pass by cooling the molten surface of the reducing flame to prevent oxidation of minor amounts of silver. During casting bullion taken probes for accurate determination of fineness. When the lever correspond with the requirements, mark stamped with a number, fineness and called refinery.

Tonnes of electronic scrap contains more gold than gold ore tonnes

TONS OF GOLD ORE TO SOME ESTIMATES ON AVERAGE contains only 5 grams of pure gold. ELECTRONIC WASTE RECYCLING contain, on average between 40 and 60% more gold. To be more precise, tons of microchip used in precision electronics, containing about 200 grams of pure gold. YET more gold to be found in TONI Mobiles, somewhere around 300 grams.

These details tell us that certain mass recycling of electronic waste we can get about 50% more gold than to recycle the same amount of 'mass' of gold ore.

To produce any portion of the electronic equipment necessary to use some of the valuable and precious metals. It is estimated that annually use more than 320 tons of gold in the production of electronics such as personal computers, mobile phones, fixed phones, navigation devices, and the like. This value exceeds $ 16 billion, while only 15% of that value at the end recycled. Everything else 'fail' in primitive Recycling operating outside the law in the harshest conditions, no logging in earnings, or craft at all.

Recycling gold is at the present time has become very popular and profitable as a business. In fact, digging up gold from the mines is quite unfavorable for the environment, costly and dangerous to human health. On the other hand, recycling is done in much more favorable conditions, carries with it a certain amount of danger, but in the end it still acceptable recycling from the excavation of gold ore.

To recycled gold from electronic waste is required to use heavy machinery, specially designed for this type of work. It is still necessary to establish a chemical laboratory in which hazardous chemical processes taking place for the removal of gold from other metals and elements in this process are not interesting. And finally the furnace in which the threshold of golden ingots of real gold with features that speak of the volume or weight of gold bars, and the purity of gold.

How many gold diggings harmful to the environment and can see yourself knowing that at the recent Swiss referendum banned digging up gold in the country because it harms the environment. Imagine, a country that has huge amounts of gold collected from all over the world refuses to herself excavate gold from the mine.

How much gold can be obtained from computer waste?

Amount of electronic and electronic waste increases from year to year, proportionate advancement of technology and our ever increasing dependency on a variety of electronic devices.

We all want to have a new computer with new components, like cell phones or some of the tablet which was introduced audiences. All the above mentioned devices contain a certain amount of pure gold, and besides gold in them to be found and other metals, precious metals and ultimately valuable metals.

Each part of the electronic waste contains materials that can be recycled, and the industrial application in the production is very important that these materials are separated, grouped, recycled and used again in production.

Recycling of electronic and electronic waste is of great financial importance. To have an idea of the need to recycle gold, here's an interesting fact.

One metric tons of electronic waste that is collected from personal computers contains more gold than 17 tons of gold ore.

Metals can be found in old computers are: aluminum, antimony, arsenic, barium, beryllium, cadmium, chromium, cobalt, copper, gold, iron, lead, manganese, mercury, palladium, silver, zinc and others.

Many of these metals are hazardous to the environment and human health, such as arsenic, cobalt, lead, mercury and selenium.

If we talk about recycling computers and computer equipment needed to know that the motherboard, processor chip, various graphics, network and sound cards contain large amounts of gold, silver or some other precious metal. When we say large amounts of gold, then I think the comparison with other computer components, such as monitors, power units and the like.

One metric ton of electronic waste (processor chips, motherboards, various card) contains between 80 and 1500 grams of gold. Apart from gold in that amount of electronic waste can be found between 160 and 210 pounds of copper, which is also being sought after metal.

The price of gold, the quest for gold - the recycling of electronic waste

Gold has always been one of the most acclaimed METAL MAN KNOWS. THESE DAYS price and demand for gold is increasing and the assumption is that this trend will continue to grow.


The price of gold has led to the recycling of electronics and other devices containing gold has become a profitable business. Recycling electronics and electronic devices is profitable even if it is in a 'cottage industry' or lesser extent.

Recycling of gold today is the search term on the Internet. A lot of people in this crisis resort to selling your old jewelry, broken necklaces and so on, but however there are those businessman who wish to make a trade in gold business.

Specifically, recycling electronic waste and production of gold from it can be a very lucrative business.

Demand for gold has become so strong that the sale of the finished product does not need to worry. Your only problem is how to correctly recycle waste and get gold from him?.

Try to find answers to questions online or some old books. One link to explains much, but not all things related to waste collection, separation, recycling of gold and sell gold is www.goldinpc.com.

If you want to turn a little more detailed and specific study issues related to the recycling of waste and production of pure gold out of it and then look for other sources on the internet. Older books can be very useful if you want to engage in extraction of gold from waste.

Specifically melting gold with other metals, and the 'dirt' is made with acid, so this job is considered extremely dangerous. Acid used in dissolving gold quite well known and are used only for that purpose, however due to the characteristics of these acids should be very careful.

The most famous gold dissolution acids called aqua regia. It is essentially a mixture of two other great acid that dissolves the gold. It is interesting that neither of these two acids can not melt gold alone, yet in the common actions acids react with gold and decompose it into a solution.

Two aqua regia acid-forming or imperial water are nitric and hydrochloric acids. The compound consists of two concentrations of acid in the ratio 1:3. Aqua regia next gold can serve as a solvent and platinum, and other precious metals. It should be noted that the aqua regia will dissolve silver, namely with him forming an insoluble chloride.

Inform yourself before you offer to buy gold

Before your funds offered to buy you need to know some facts. State of the market, competition among buyers and estimation of gold items that interest you. To prevent fraud, or to get a fair price for your gold, and it is necessary that you know something about the gold market in the world.

In fact, gold is considered one of the best 'keeper value' of a state bank, or a person's personal values. Throughout history shows that gold is far more stable currency than the holder of paper money or coins from a non precious metal.

Old gold coins 'coins' which was used in the 19th and 20 And today has a value of gold of which was made while the paper money of the old member collapsed at a time when the state itself.


Dealers who deal with buying gold and know the dynamics of the psyche of people who sell their gold pieces. They know that people generally decide to sell gold at a time of great tribulation. We point this out because the human affliction buyers to take full advantage. If you come to sell gold jewelry piece, and by the way, and told the purchaser that you rush for money, then you are an easy target for the 'plunder'. This is especially true for people who actually do not know the value of the property 'gold' they sell.

To be clear, the dealers are doing their job and should not blame them if they want to take away a better opportunity. If you show that you are a naive they will use it, also see if merchants to talk and negotiate with someone who is familiar with the subject matter, the trade will take a lot more professional and fairer for both parties.

When you offer your gold to sell, do not show weakness in the sense that you are in a hurry to sell, or you do not know where the price of gold is about. In general, the value of gold that you can calculate for yourself, and it is less difference that may arise between this price and offered for purchase is earning buyer.

If you sell gold coins, cash should be aware that the price is not determined only by the weight and purity of gold from which they are made the objects. Numismatists such cases, older coins and gold coins, and gold coins are valued separately. Because of this, it is important first to address some of the coin and ask for an offer before contacting the purchaser of gold.

Tags for purity of gold, types of gold, how to identify gold?

Everyone has heard of the gold and most know that there is a white gold. However, few can explain what it is white gold?


White gold is an alloy name that ultimately has a white color. We know that gold is yellow in color, and jewelry that is made of an alloy of gold and other precious metals or ordinary. The same is true for white gold. In fact, white gold is an alloy of pure gold and a metal that would later give white what we see.


White gold color similar to the silver color just a little darker, perhaps more matte colors. White gold and the 'usual' ranges and there are a mix of gold and some metals. We have for example white gold alloy which consists of a mixture of gold and nickel, which has a strong structure suitable for the production of rings, pins and the like. For example, if gold mixed with palladium then we have a soft and pliable ideal for shaping metal in jewelry and as a foundation for gemstones.

The value of white gold


Price or the value of white gold is reflected as in 'ordinary' yellow gold, per unit of pure gold in an alloy. As we have written in the text above, white gold is an alloy of gold and some white noble or ordinary metal. If we want to estimate the value of gold in a piece you need to know the total weight of pieces and the proportion of pure gold in it. If it comes to jewelry then usually somewhere in the back of a label purity of gold pieces, so it is easy to estimate its value. However, if the label is damaged, or no time to do a test with acids that shows us where the purity of gold is concerned.


Tags for purity of gold


Tags for purity of gold to be telling us what percentage of pure gold in an alloy. We have, for instance gold piece marked 585 contains 58.5% pure gold. If we want to calculate the value of the pieces it needs to be weighed, and the weight and take a 58.5% value and multiply it by the price of gold per gram.

Recycling team saying - Gold is in the trash!?!

The amount of gold in electronic waste is up to fifty times larger than those that can be extracted from the ore of gold. These data have experts in recycling gold from electrical waste.
Waste disposal is becoming one million jobs. Raw materials that are hidden in the worn electronic waste are needed to manufacture new devices. Demand for modern electronic devices and gadgets is increasing, so it is assumed that it will use in the production of gold to go up.


We produce about 1.3 billion cell phones, and only 10% end up in waste recycling. This data suggests that people annually throw 20-22 tons of gold in the garbage and they did not even realize it.
Did you know that the average user changes his computer every two years?
That in 1998. year in America, thrown 21 million PCs, while for 2005. The forecast figure of 315 million?


Large companies have come to realize that the more they pay to come to recycle materials from old computers and hardware rather than buy new (latest studies have shown that recycling saves at least 240 billion U.S. dollars per year).
Electronic waste currently represents one-quarter of the world of waste - and that number increases every three years by 30%, and only 10% is recycled properly. That is why the Association for the Preservation Agency (EPA) under contract with major hardware manufacturers, initiated the action "Plug-In To Recycling 'and enabling mek bargain recycling.

What exactly is electronic waste and why it's good to recycle?

Electronic waste is an informal but very popular name for all electronic devices at the end of its service life. Because of harmful chemical compounds that these devices contain they fall into the category of hazardous waste, and as such are disposed in specially prescribed containers and later recycled in special recycling stations.

Chemical compounds that can be found in electronic waste are: silicon, cadmium, arsenic, lead, mercury, chromium, beryllium, phosphorus, and some others.

Cadmium is commonly found in personal computer motherboards and motherboards are incidentally the most wanted material for recycling because it contains a large percentage of gold.

Lead is often found in a variety of monitors, and its purpose is to reduce the radiation monitor while working.

Phosphorus is found in CRT, so we can conclude that this element can be found in almost all older monitors known as CRT.



How to recycle electronic waste?

Sony Corporation, the company came up with the idea that instead of dismantling the old electronic equipment, in the same store the old abandoned mine openings. Some of these holes in themselves and can accommodate up to 70 million computers, and later I'd be in that so-called urban ore could remove metals such as copper, gold, iron, glass, and finally for digging and plastics and other nonmetallic elements.

Computers contain a higher percentage of copper than copper ore. For one ton of copper is necessary to dig up and recycle 19 tons of raw material in the form of stone that is covered with these metals.

Mentioned the idea still stands as an idea, as long as they are looking for better solutions for the recycling of waste that is still going on dismantling and sorting of parts that are later recycled.


Four methods used to recycle electronic waste are:

- Dismantling equipment, manual separation of parts that can be reused in the production

- Mechanical removal, removal of harmful components and then chopping and cutting to remove usable parts, such as plastics and metals demand

- Burning and prečišćivanje, having burned fuel components can be extracted metals

- Chemical Processes, noble metals can be removed from the printed circuit board through various chemical processes. Most famous chemical processes for the recycling of gold from electronic is to use compound aqua regia or royal water.
