How Gold Is Mined Gold Mining Process World Gold
The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity known as doré typically containing between 60 90% gold.

Gold is then leached from the carbon particles by a strong solution of sodium cyanide and sodium hydroxide, and it is recovered from solution by electrowinning directly onto steel wool or by the Merrill Crowe process. In the latter process, the gold bearing solution is deoxygenated and passed through a filter press, where the gold is displaced from solution by reduction with zinc

this mining operation. The process is currently unprofitable with a gold price around $300 per ounce. Process Description Unit 100 Size Reduction of Ore The BFD of the overall process is shown in Figure 1. The PFD for Unit 100, shown in Figure 2, is designed to reduce 41.5 tons/hr of gold ore from a feed range of 2 5 to 160 microns. The mined ore is fed using a Grizzly
