Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative.Apr 06, 2016 Unfortunately, gold cyanidation was ineffective on refractory gold ores which are made up of sulfide minerals that block the cyanide solution extracting the gold. An older, and very hazardous, extraction process called roasting was adapted and improved to work with this type of gold ore.

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.
