Gold mining is the process of removing gold from nature. Placer mining and hard rock mining are two forms of gold mining. Placer mining uses tools to collect gold nuggets and flakes from water.
By 2000 bc the process of purifying gold-silver alloys with salt to remove the silver was developed. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower. By ad 100, up to 40,000 slaves were employed in gold mining in Spain.
Modern industrial gold mining destroys landscapes and creates huge amounts of toxic waste.
