Hard Rock Mining Gold and Silver Ore and processing it

In most gold ores, the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold. Cyanide, in the presence of oxygen actually dissolves both gold and silver. It is both efficient and inexpensive, so it is widely used in precious metal ore processing. Properly done, gravity concentration followed by flotation (where necessary) and then cyanide will recover

Recovery of gold from sulfide refractory gold ore: Oxidation roasting pretreatment and gold

 · Typically, gold is encapsulated or finely disseminated in refractory gold ores and the direct cyanidation is not effective for gold extraction from these ores, even after the ore is ground to exceeding small particles (Nazari, 2022, Corrans and Angove, 1991).Especially for sulfide refractory gold ores, in order to recover gold, many oxidation pretreatment technologies were proposed including

Extraction of Gold

The extraction of gold by the cyanide-method is of great technical importance. It is effected by lixiviation with a solution of potassium cyanide, the gold being precipitated either by addition of zinc or electrolytically. The process was suggested by Mac Arthur and Forrest in 1385, and is based on the well-known solubility of gold in potassium-cyanide solution, a phenomenon said to have been
