Artisanal Small Scale Gold mining (ASGM) Artisanal and small scale gold mining (ASGM) is a complex global development issue. ASGM uses substantial amounts of mercury in mineral processing usually in highly unsafe and environmentally hazardous conditions. Mercury is used to bind the gold to form an amalgam, which helps separate it from the rock, sand and other materials.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its Gold Cil Processing Line
Mineral dressing (= Orebeneficiation) The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate

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.
There are 29,594 gold mining equipment suppliers, mainly located in Asia. The top supplying countries are China (Mainland), India, and Turkey, which supply 99%, 1%, and 1% of gold mining equipment respectively. Gold mining equipment products are most popular
Gold content is very low in ore. To extract gold, need crush and grind ore and use mineral processing technology to pre concentrate or separate gold. For gold dressing, the gravity separation, flotation and cyaniding are widely used. The CIL are widely used in Africa.
