Mercury-dependent artisanal and small-scale gold mining (ASGM) is the largest source 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 a torch or over a stove-to dist …

Small scale mining, some info. Small Scale Mining Info. Generally, the beginning and the end of most small scale mining attempts, is the prospecting phase. This is because most prospectors are not geologists and have not had the experience and education required to comprehend the nature and origin of mineral and metal deposits in the earth.
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. For this technography, the following phases and aspects were identified and querried: Prospection.
The Commercially Viable Conflict Free Gold (CVCFG) Project, an artisanal mining initiative funded by the United States Agency for International Development (USAID), aims to establish a conflict-free artisanal and small-scale mining (ASM) gold supply chain originating from eastern Democratic Republic of the Congo (DRC).
"The high gold prices probably made artisanal mining worth the labor." The team calculated a correlation between gold prices and annual mining conversion after a two-year lag. Over the study period, the value of gold jumped from about $700 per ounce to as high as $1,700 in 2012; it is now nearly $1,800 per ounce.
Background: Artisanal and small-scale mining activities are widely practiced globally. Concentrations of heavy metals associated with gold, such as copper (Cu), zinc (Zn), arsenic (As), cadmium (Cd), mercury (Hg) and lead (Pb) can increase in the environment as a result of mining activities, leading to environmental pollution and pose toxicity risks to humans and animals.

Artisanal and Small-Scale Gold Mining Without Mercury. In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant ...
