Extraction of gold using cyanide

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.

Gold extraction - Wikipedia

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...

Abstract. Alchemists—driven by greed and curiosity—did not manage to produce gold from cheap materials, but they certainly initiated and advanced chemical knowledge. The discovery of aqua regia by the Arab alchemist Jabir Ibn Hayyan in the sixth century introduced a chemical technology for the extraction of gold from its ores.
