Gold Mining Operation: 10 - 30 years. 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.
Currently, the thiosulfate gold leaching operation at the Goldstrike mine, Nevada, of Barrick Gold Corp is the only large-scale gold extraction plant with an alternate lixiviant (Azizitorghabeh et al., 2021). Although research on sulfur-containing lixiviants has been the most common in gold hydrometallurgy in the past three decades, few ...
