Though found in only very small quantities, the concentration of gold in electronic waste, such as computers and mobile phones, is 80 times higher than that found in natural gold ore. In fact, electronic waste is thought to contain as much as 7% of the world's gold, and up to 300 t of gold is used to produce new electronics every year.

A clean hydrometallurgical process has been developed to efficiently and economically recover selenium, copper, gold, silver and lead from a copper anode slime. The mixture of H 2 SO 4 and H 2 O 2 was demonstrated to be effective for selenium leaching based on their synergistic effects, and the potential synergy mechanism was proposed.

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
