The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks …
Gold is mined in the form of microscopic particles in concentrations as little as 0.5 parts per million (ppm). As a result, simple tools have been replaced by complex equipment and chemical processes to extract gold. Today, one of the most popular methods for gold extraction is the Merrill Crowe process. The process can be summarized as follows:
These metals could be lead or copper. For these reason some polymetallic deposits contains important amounts of gold. When we have to talk about gold mining, everybody thinks on free gold. This idea started at the first days of gold deposit processing. The gold from original veins was gradually disintegrated through the time.
