Artisanal mining can include activities as simple as panning for gold in rivers, toplex as development of underground workings and small scale processing plants. In any of these circumstances, issues can stem from difficulties in achieving regulatory oversight of a large number of small operations including issues such as security of land tenure for artisanal miners, to enforcement of environment, safety standards, and labour standards.
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:
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 mercury exposure and health risks.

Gold is mined in two ways one on hard rocks where gold found embedded in quartz vein is extracted using simple tools. Mined ore is then crushed either manually using a hammer or by a crusher.
Small scale gold mining isnt 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.

Metals you can extract include: gold, silver or other of the precious group as well as the classic base metals copper, lead, zinc, nickel, molybdenum. Much of our ultra small scale equipment allows you to process from just a few kilo pounds per day and work on your passion for a small budget.
11/05/2018· Mercurydependent artisanal and smallscale 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 heatedoften with a torch or over a stoveto distill the mercury and isolate the gold.
Small Scale Miners Our vision is to enable small scale gold miners to achieve the same gold recovery rates as large scale miners but with a lower cost, scalable, mobile processing plant. Small scale miners can find it difficult to operate profitably. In Australia alone, 85 of gold tenements are inactive.

Small scale gold mining is the largest anthropogenic contributor of mercury pollution on Earth. The miners grind gold ore together with mercury in order to recover the fine gold grains. The gold amalgam is burned whereby the mercury evaporates and gold is left behind. This processing extracts only a fraction of the gold in the ore and the released mercury causes serious global health
