The Borax Method of Gold Extraction for Small-Scale Miners

An obvious drawback of this method is the toxicity of mercury.2,3 The health risk of mercury is well known today in many parts of the world, but in remote small-scale mining (SSM) communities that knowledge is still scarce.4 Gold extraction by amalgamation releases large amounts of mercury into the environment as metal mercury, which is later transformed to metholated mercury, a powerful ...

Dredge No. 4 National Historic Site

the mining of stream bed (alluvial) deposits for precious metals. Unlike a hard-rock gold mine, the precious metal is already 'loose' in the ground and requires only the action of water and gravity to separate. The principle is the same with a gold pan as with a dredge. Riffles are devices used to trap gold in a sluice.
