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.
