The Mercury Problem in Artisanal and Small-Scale Gold
Graphical Abstract. Mercury rising: The intentional use of mercury in artisanal and small-scale gold mining directly impacts the health of millions of people globally. Collaborative input from the chemistry Over $4 million from the Global Environment Facility is being used to teach best practices, help miners access financing and to move towards mercury-free mining.

Artisanal and Small-Scale Gold Mining Without Mercury
Although many miners use mercury in artisanal and small-scale gold mining, it is possible to safely and economically recover gold without it. Mercury-free techniques are safer for miners, their families and local communities. They may also help miners market their gold at higher prices. Many artisanal and small-scale miners are We estimate that artisanal and small scale gold mining releases between 640 to 1350 Mg of mercury per annum into the environment, averaging 1000 Mg yr -1, from at least 70 countries. 350 Mg yr -1 of this are directly emitted to the atmosphere while the remainder (650 Mg yr -1) are released into the hydrosphere (rivers, lakes, soils, tailings).World emissions of mercury from artisanal and small scale gold mining

Mercury (element)
The purest of these was gold, and mercury was called for in attempts at the transmutation of base (or impure) metals into gold, which was the goal of many alchemists. [21] The mines in Almadén (Spain), Monte Amiata (Italy), and Idrija (now Slovenia) dominated mercury production from the opening of the mine in Almadén 2500 years ago, until new deposits The use of mercury in artisanal and small-scale gold mining (ASGM) is one of its least favourable applications.

The Use of Mercury in Artisanal & Small Scale Gold Mining
The use of Mercury in Artisanal and Small Scale Gold Mining. Circle back to ASGM: mercury is highly important for this sector but often poorly handled, putting communities and the environment at risk. The Minamata Convention, one should hope, would reduce the consumption, however this is not evident. The latest UN Global Mercury Assessment The mercury poisoning of Atehortua reflects a growing threat in Colombia and other parts of the world as small-scale gold mining expands in response to rising gold prices. Gold and mercury are interdependent commodities. When the price of gold increases — as it has since 2002 — so does mercury pollution.Threat of Mercury Poisoning Rises With Gold Mining Boom

New technology to combat mercury use among Indonesian gold
The introduction of this new mercury-free technology is part of a long road to achieve widespread practice of responsible and safe mining, a key objective of UNDP’s GOLD-ISMIA project. Funded by the Global Environment Facility (GEF), the Project also works in partnership with the Ministry of Environment and Forestry.Mercury is a pervasive and harmful feature of the biosphere. To a great extent, the presence of mercury in the environment is a consequence of gold mining practices past and present although the linkage is not easy to recognise without a historical framework in place.

Developers strike contamination from Virginia gold mines
The U.S. Environmental Protection Agency’s Superfund program cleans up some of the nation’s most contaminated lands. The Virginia Energy report also noted that most of the gross tonnage of gold extracted in the state between 1832 and 1860 came from the Vaucluse Mine. Mining records indicate Henry Ford bought the gold mine at one Step 2: Processing The Crushed Ore. For most artisanal gold miners, step 2 involves the use of toxic mercury. At this mining site, ore is placed under large boulders along with toxic mercury. A man then stands on the boulder, rocking back and forth, sometimes for hours.In Photos: Teaching Artisanal Gold Miners To Extract Gold Without Mercury
