The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use. New technologies can benefit the mining industry and consumers in all stages of this life cycle. This report does not include downstream processing, such as smelting of
Some gold can be found by panning in rivers; heavy gold will remain in the pan, whereas lighter rocks and minerals float out. This smallscale form of gold mining has little effect on the body of water, but the largescale practice of mining gold from ore can have tremendous negative effects on water quality.

Gold ore processing instruction. Currently, the mainstream gold ore process generally is crushed by crusher, crushed again by gold ore crusher, and then goes through sorting machine, blending machine, chute slipway, flotation machine; next, gold ore processes by gravity and flotation, and then extracted the concentrates and tailings, and then applies ore reagent by chemical method, finally by
In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the goldbearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to

In many countries, elemental mercury is used in artisanal and smallscale gold mining. Mercury is mixed with goldcontaining materials, forming a mercurygold 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.
