For millennia mercury has been indispensable to ASGM as it allows them to isolate gold in their mining process. Liquid mercury is added to the crushed ore where it binds with tiny particles of gold then is clumped into amalgamated pellets that workers heat, vaporizing the potent neurotoxin mercury into the atmosphere, leaving behind the more concentrated gold.
Abstract: Mercurydependentartisanaland smallscale gold mining (ASGM) is the largestsource of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated—often with atorch or over astove—todistill the mercury and isolate the gold ...
Mining Mercury in Nevada Gold recovery utilizes thermal processes that volatize Hg. Nevada has ~50 permitted mines; ~25 with various thermal processes. Mercury is *not* used or added for gold recovery.
Mercury was imported, refined, and then exported for global use in chlorinecaustic soda production, dental amalgam, fluorescent lights, and smallscale gold mining. Some buttontype batteries, cleansers, fireworks, folk medicines, grandfather clocks, pesticides, and skinlightening creams and soaps may contain mercury.

Gold mining is common in smallscale communities in over 50 countries around the globe. Ore containing gold is ground to a fine sludge. Liquid mercury is added to this mass and a small piece of amalgam, containing approximately 1/4 gold and 3/4 mercury (Hg) is formed. To obtain the required gold, the amalgam is heated either by laying it
Price History. The price of gold in the free market because smallscale gold mining uses mercury in processing the precious metal. Basically, the higher the gold prices, the higher the mercury prices although there are also exceptions to the rule of thumb. The .
Mercury is also extensively used in the gold mining process as an amalgam for separating gold from ore. When mercury is combined with gold silt, it causes a reaction that separates the gold from the ore. This amalgam is then heated in order to evaporate the mercury and leave the gold pieces. If done without the proper safety equipment, this process can release mercury vapor into the air and can also discharge .
