  • Mining : What Is Gold Mining? How Is Gold Mined?

    Gold is mined using four different methods Placer mining, hard rock mining, byproduct mining and by processing gold ore Placer mining Placer mining is the technique of extracting gold accumulated in a placer deposit often recover together with copper considerable amounts of gold and other metals Some sand and gravel pits, such as thoseColombia has a long and rich history of gold mining, dating back to the preColonial era (Brooks et al, 2016)Gold mining is an important economic driver in the impoverished rural regions in Colombia, with around 300,000 miners working in the artisanal and smallscale gold mining (ASGM) sector on a mainly subsistence basis, producing an estimated 54 metric tonnes (Mt) of gold annuallyThe impact of artisanal gold mining, ore processing andThe Process: Mining Gold with Mercury microbeads of mercury are dispersed in the fine sand and water and can be carried far from the mine when discharged in water courses 22 Many thousands of tonnes of tailings are generated each year in ASGM and removing mercury and recovering residual gold are critical problems in tailing processingThe Mercury Problem in Artisanal and Small‐Scale Gold
