May 18, 2009Once the ore has been liberated from the ground, the gold will need to be extracted. The processing consists of taking the big pieces of ore and making them smaller, until it reaches the consistency of beach sand. At this point a cyanide solution is added to the mix and milled further into a muddy, watery mix.

The final category of gold mining is the processing of Gold ore. This method is largely becoming deprecated as the yield of Gold is often very low and the environmental impact and costs of the operation are substantial. The Gold ore is finely crushed rock or earth containing trace amounts of Gold which are extracted using a chemical process.

How Is Gold Extracted From Gold Ore? Sciencing

Another process involves ground ore being passed over plates which are coated with mercury. The gold and the mercury form an amalgam, leading to the name of the process, amalgamation. Once the amalgam has formed, it is heated until the mercury gas is boiled off, leaving the gold. The mercury gas is highly toxic and must be handled carefully.

May 24, 2019Gold extraction refers to the methods used to remove gold from its raw state in gold ore. A number of processes are employed to achieve extraction, including separating the gold from its surroundings by physical force, exposure to heat, or chemical means. The ore is typically mined first, though this is not always necessary, and then subjected

Extracting Gold  HowStuffWorks

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.
