The artisanal gold council works globally to improve the health, economy an devironment in artisanal and small scale mining. We design and implement affordable and intuitive mercuryfree processing and training systems for the Artisanal Gold Mining Sector.
Many artisanal and smallscale miners are achieving high rates of gold recovery without mercury, benefiting their health, the health of their communities, and the environment. On this page, we summarize some of the techniques in mercuryfree artisanal and smallscale gold mining.

CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): This article discusses the technical evolution observed worldwide in the artisanal and smallscale gold mining (ASGM) sector. At first glance, the centralization of mineral processing activities in local centers seems to rationalize the production and educe the dispersion of polluting tailings in rural areas.
polluting tailings in rural areas. However, the rise of processing centers around the world is taking advantage of the ignorance and lack of capital of the artisanal miners. These centers receive gold ores from miners and process using poor grinding and amalgamation processes to extract less than 30% of the gold.
The aim of this paper is to reflect on efforts made worldwide to construct processing centres where artisanal miners can visit to have gold extracted from ore free or for a nominal fee. These centres use inefficient grinding and amalgamation processes to extract less than 30% of the gold
in gold processing; and to establish a mercuryfree gold processing demonstration center in Busia ZIMBABWE In Zimbabwe, the sector of smallscale, artisanal gold mining surpasses that of largescale gold mining. Furthermore, 84 % of ASGM activities are unregistered as required by the national Mines and Minerals Act.

Mercury Free Gold Processing. By Kevin Telmer April 23, 2017. Using mercury amalgamation to separate gold particles from ore is not only dangerous to the health and environment of miners and their families but it is also inefficient. Recovery is an important aspect of efficiency in mining.
Gold Processing? Mercurygold amalgam burned during gold purchasing secondary processing of gold doree which still has mercury content of 5 20% Typically little or no control of emmited airborne mercury Regional funnel points for ASM gold production Located in regional economic centers Located in regional population centers
#0183;#32;The Shamva Centre in Zimbabwe, built in 1989 to process ores from 40 gold mines in the region, was another example of organized processing centres. The centre was created out of an initiative by the National Miners Association of Zimbabwe with the UK NonGovernment Organization ITDG (Intermediate Technology Development Group, nowadays known as Practical Action).
