The common definition of “refractory” gold ores, are those ores that do not allow the recovery of gold by standard gravity concentration or direct cyanide leaching. One major category of refractory ores are gold values contained within the crystalline structure of sulfide minerals such as pyrite and arsenopyrite.
In ores, gold occurs mainly in the free (native) state and only very rarely forms minerals with selenium, tellurium, antimony, and bismuth. Pyrites and other sulfides frequently contain an admixture of gold, which is extracted in the processing of copper ore, complex ores, and others.

Gold ores are classified “free-milling” and “refractory” based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory gold-bearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of gold-entrapment in different associated mineral phases before an appropriate.
