GOLD MINING OPERATION. Gold mine's mining operation represents the stage during which ore is extracted and processed into gold, which can take between 10-30 years. In order to process gold, rock and ore must be transformed into a metallic alloy with a substantial gold content - called doré - typically in the range of 60-90% of gold.
