When present in sulfide ore bodies, the gold, although still elemental in form, is so finely disseminated that concentration by methods such as those applied to alluvial gold is impossible. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earth’s crust.

You can use Mohs tests in the field to determine the ore characteristics and see if that jives with what the Mohs test has to say about gold ore. Though rather rare, gold does appear in forms other than pure nugget or string. It can be mixed in with the minerals calaverite, kennerite, and silverite. On the Mohs scale, calaverite has a hardness

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.
