Mercury Usage in Gold Mining and Why It Is a Problem

Jul 22, 2019  Most large-scale and regulated gold mining companies do not use mercury in their mining operations. However, Small-scale and illegal gold mining operations will sometimes use mercury to separate the gold from other materials.

Artisanal and Small-Scale Gold Mining Without Mercury ...

In some jurisdictions, mercury use may be illegal or restricted in certain ways. The Minamata Convention on Mercury, a global agreement for reducing mercury pollution, recognizes the risks of using mercury in artisanal and small-scale gold mining, and calls upon nations to reduce, and where feasible eliminate mercury use in this sector.

Mercury Use in Small-Scale Gold Mining

Mercury is very often used to extract the gold in this small-scale method of gold mining. The result is that ASGM causes the largest single “intentional-release” of mercury in the world. Because this type of mining is often unregulated, there arises a danger to the workers via

Artisanal mining - Wikipedia

An artisanal miner or small-scale miner (ASM) is a subsistence miner who is not officially employed by a mining company, but works independently, mining various minerals or panning for gold using their own resources. Small-scale mining includes enterprises or individuals that employ workers for mining, but generally using manually-intensive methods, working with hand tools.

Gold mining - Wikipedia

Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Large-scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small-scale gold mining (ASGM), often clandestine, gold prospecting.
