Designing gold project flowsheets | Metallurgy & Mineral Processing

It has been said that gold was one of the first metals to be mined. As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated. Gravity was the first method developed to recover gold from ore. But, currently there are very few deposits.

Mineral Processing - KCGM

Golden Mile ore is of two main types: weathered oxide ore from near the surface which is free-milling with the gold easy to extract, and sulphide ore in deeper ore bodies where the majority of the gold is locked as inclusions in tellurides and pyrites and is difficult to extract. In the sulphide or telluride ore, the gold is chemically.

Sulphide Gold | Gekko

Because cyanide cannot always leach sulphide-associated gold, regrinding the ore is typically required to expose the free gold for recovery by intensive leaching. Critically, the size at which one can efficiently liberate gold from the host mineral of the particle will determine the process to use for optimal gold recovery.
