Gold Mining: Gold Mine Operations World Gold Council

2021-8-25  Gold Mining Operation: 10 - 30 years. The gold mining operation stage represents the productive life of a mine, during which ore is extracted and processed into gold. Processing involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold.
