How gold is mined
How gold is mined Gold mining is a complex process that involves several stages, beginning with exploration and ending with refining. The process starts when geologists search for gold deposits using geological surveys, satellite imagery, soil sampling, and drilling. Once gold is discovered in quantities that can be mined profitably, mining companies or small-scale miners prepare the land by clearing vegetation and constructing access roads. Environmental assessments are often carried out to understand and reduce potential harm to surrounding ecosystems and communities. The method used to extract gold depends largely on where the gold is located. In many regions, especially in river areas, artisanal miners use traditional techniques such as panning and placer mining, where water is used to separate gold from sand and gravel.

The ore is first crushed and ground into a fine particles to release the gold from the surrounding rock. The next step is gold processing, which separates gold from other minerals. One common method is gravity separation, where heavy gold particles are separated using a water and specialized equipment. Another widely used method is cyanide leaching, where a chemical solution dissolves the gold from the crushed ore
