2009-8-27  The carbon in the reactor into which pregnant pulp is fed (referred to as the first reactor) becomes highly loaded with gold. Loaded carbon values on operating plants range from 300 to 20 000 grams of gold per ton of carbon, a concen-trating factor of about 1 000–1 500. A portion of the loaded carbon is periodically removed from the first ...

AARL Carbon Stripping System Operation: Elution ...

2016-3-31  The gold room uses the Anglo-American Research Laboratories stripping system to strip gold from loaded carbon in batches of approximately 1.9 tonnes. The process is fully automated and controlled by electronic sequence controllers which

Gold and climate change: An introduction World Gold

2018-6-26  Gold is rare and, as with other precious metals, a lot of ore is mined and processed to produce small amounts of pure metal. The gold production process therefore uses a relatively high level of energy to bring finished gold to market and has a higher greenhouse (GHG) emissions intensity per tonne of finished product than many other bulk metals.

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.
