Gold Mining: Gold Mine Operations World Gold Council 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. What does Gold Look Like in Nature? Identify Real Gold Many ores that contain gold contain other metallic metals in them also,so there are likely to be a lot of shiny minerals mixed into the rock which may or may not be valuable.The other challenge in visual inspecting gold ores for possible gold content is the fact that the total concentration of gold in a piece of ore is generally negligible.
