Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen.The lustre of the pure metal is due to its electron configuration, which results in its reflecting all electromagnetic radiation of wavelengths longer than 3000
"The mining of e waste, and production of pure metal ingots from it of copper or gold, promises to be a very profitable business," said Macquarie's Prof John Mathews.
Natural gas is often found alongside petroleum.In fact, one third of all platinum is mined as a byproduct of nickel mining. Gold, silver, copper, zinc, and lead often come from the same mine. The
Most lithium is commercially produced from either the extraction of lithium containing salts from underground brine reservoirs or the mining of lithium containing rock, such as spodumene. Lithium production from clay sources is expected to become commercially viable, though perhaps not until 2022.
Sulfuric acid is a byproduct of copper cathode refining a ton of cathode yields three tons of sulfuric acid. Since the start of the year, the sulfuric acid price has doubled from the average in 2009 to CNY400 a metric ton, high enough for copper smelters to squeeze some profits from their refining activities, industry participants said.
