In fact, Artisanal and Small Scale Gold Mining (ASGM) is a key actor in global mercury consumption, using it to separate gold from other sediments. In the mix, mercury binds the gold in an amalgam, which is then heated up so that the mercury evaporates and the miners are left with a gold nugget. Many artisanal miners operate without protective ...

Ending the toxic trail of small-scale gold mining
The project aims to reduce mercury use in small-scale mining by an estimated 369 tonnes and has already equipped thousands of miners with greater understanding of safer mining practices. PlanetGOLD is set to expand to an additional 15 countries and leverage co-financing of over US$342 million during its second phase in 2023.
The Mercury Problem in Artisanal and Small-Scale Gold Mining
While mercury amalgamation has been used for thousands of years to mine gold and silver, 2 it is unfortunately still a widespread technique in present-day artisanal gold mining. Mercury is abundant and inexpensive, sourced through a variety of industrial supply chains or mined directly from cinnabar, making it a readily available tool for ...
Gold Mines Fact Sheet
production facilities, the seventh largest source of mercury air emission in the United States. • We estimate the final rule will reduce mercury emissions by 1,460 pounds per year (down to about 1,200 pounds per year), or about a 77 percent reduction from 2007 levels. • Gold ore processing and production facilities extract gold from mined ore.
The Role of Mercury in Gold Refining
Mercury dissolves many other metals, and is especially effective on gold and silver (platinum is actually quite resistant to this phenomenon). When mercury dissolves another metal, the resulting mixture or alloy is called an amalgam – which is useful for many aspects of precious metal refining. Most pre-19th century placer mining …
