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.

The initial step in the gold refinery process involves the extraction of gold ore from the ground. This is done through mining methods that depend on the location, accessibility, and quality of the ore deposit. Underground mining techniques, such as tunneling and shaft mining, are employed to extract gold ore from deep within the Earth.
Intensive cyanidation is a good option, but obviously, the material can be sent to the leaching process employed to treat the raw ore. Gold and silver recoveries are between 99.5 to 99.7%. Although slag production weight is variable, a typical operation can generate 10 kilos of slag per 1000 oz of gold.
