Copper Mining and Extraction: Sulfide Ores

An ore is a rock or mineral that has enough metal in it to make it worth extracting. At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. Gold, silver, platinum and tin are insoluble in this electrolyte and so do not deposit on the hode. They form a valuable 'sludge' that

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
