2021-8-9  Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging. Gold panning is mostly a manual technique of separating gold from other materials.

Artisanal and Small-Scale Gold Mining Without Mercury US

2021-8-7  In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.

Mercury Usage in Gold Mining and Why It Is a Problem

2019-7-22  How Mercury Is Used in Gold Mining. First, mercury is mixed with the materials containing gold. A mercury-gold amalgam then is formed because gold will dissolve in the mercury while other impurities will not. The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold.
