Gold mining involves the extraction of gold either via conventional mining or via placer mining, as it is a soft metal, gold is relatively easy to separate from its surrounding. Global gold production is estimated at approximately 4,000–5,000 metric tons per year, with the majority coming from newly mined sources. Historically, gold mining from alluvial deposits used manual separation processes, such as gold panning. The expansion of gold mining to ores that are below the surface has led to more complex extraction processes such as large scale pit mining and chemical extraction processes such as gold cyanidation. The history of gold mining dates to at least 4700 BC, with gold being an important metal mined in pre-history and early civilizations around the world. In empires like Rome and Egypt, gold mining would be a source of wealth and power for governments. Gold rushes have been driving forces of migration and industrialization in many parts of the world, starting in the middle ages in...
