Extracting Gold HowStuffWorks

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 carbon in pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

How Is Gold Extracted From Gold Ore? Sciencing

Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold

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 mercury exposure and health risks.

How and why do we produce gold and copper concentrates

In general terms, when gold is the only payable mineral present (i.e. gt;98 99% of the value), we can process the ore on the mine site and create gold bars. At both North Mara and Geita, gold is extracted using gravity techniques for the coarse, free gold and then cyanide to leach the finer disseminated gold. Gold bars are smelted at both mines.
