Activated Carbon in Gold Cyanidation
Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation. Here too, activated carbon is the catalyst for recovery of this precious metal.

2016-1-1 · The ore contains on average 1.1% sulfide sulfur, 1.1% organic carbon and 2.9% carbonate carbon. The relatively high carbon content affects the gold recovery through preg-robbing during leaching. After roasting in the CFB, the carbon content is reduced to such low levels that the gold recovery increases by approximately 20%.

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.
