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 Elsener's equation occurs: 4Au + 8CN + O 2

Biomining is used to recover gold from low grade ores mines with less than 0.2 mg kg 1 that cyanidation cannot extract. Much of that gold is strongly sorbed/bound to sulfides, silicates, carbonates, and sulfates, among others Gasparrini 1993, chap. 6 and is therefore difficult to extract. Biomining techniques have gained popularity due to
