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.

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.
