Artisanal and Small-Scale Gold Mining Without Mercury,

Many artisanal and small-scale 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 mercury-free artisanal and small-scale gold mining.How “Small” Is Small-Scale Gold Mining?,Small-scale gold mining isn’t really that small in reality. Workers employ a variety of methods and mining techniques. They pan for gold, dredge rivers, manually dig up ground with shovels, work with hydraulic systems, use mechanized crushers, and often utilize large earth moving equipment.Artisanal and Small-Scale Mining | World Gold Council,the Requirements for a clean technology in small scale gold mining (1) - the technology must be technically efficient (more than the traditional methods) Technical-economical criteria: - the equipment, if possible, needs to be manufactured locally - long life span - simple and safe handling and maintenance (also by less qualified personnel)

It covers formal or informal mining which is characterised by low capital intensity and high labour intensity and relatively simple methods for exploration, extraction and processing.Technologies for Small Scale Primary Gold Mining,the Requirements for a clean technology in small scale gold mining (1) - the technology must be technically efficient (more than the traditional methods) Technical-economical criteria: - the equipment, if possible, needs to be manufactured locally - long life span - simple and safe handling and maintenance (also by less qualified personnel)

The Borax Method of Gold Extraction for Small-Scale Miners,

An obvious drawback of this method is the toxicity of mercury.2, 3 The health risk of mercury is well known today in many parts of the world, but in remote small-scale mining (SSM) communities that knowledge is still scarce.4 Gold extraction by amalgamation releases large amounts of mercury into the environment as metal mercury, which is later,METHODS AND TOOLS,Artisanal and Small-scale Gold Mining (ASGM) Methods and Tools Version 1.0 An Artisanal Gold Council (AGC) document produced in conjunction with the UN Environment Global Mercury Partnership This publication should be cited as follows: O’Neill, J.

View Show abstractTechnography of small-scale gold mining in the Amazon –,Small-scale gold mining is usually devoted to secondary deposits as the gold, concentrated by gravity processes, is free and easy to extract. But also small scale mining practices in primary deposits can be found in the countries under study.
