In the Gold recovery process, activated carbon is added directly to the gold-bearing cyanide tanks. The cyanide dissolves the gold from the ore which is then adsorbed by the activated carbon. The loaded carbon is then separated from the solution and subjected to a desorption process to recover the gold.
In the chemical industry, activated carbons find widespread use to purify numerous products – ranging from bulk to fine chemicals (e.g. hydrochloric and phosphoric acid, methionine, pentaerythritol, tartaric acid). They are also used in the recycling of chemicals (e.g. metal plating baths and dry cleaning solvents).
Activated carbon is capable of producing large number of organic products chiefly used in biotechnology industries. Activated carbon by oral ingestion in form of tablet or capsule can help resolve gastrointestinal problems of flatulence. It is used to treat a number of oral poisonings including effect of strong acids, metal poisoning and organic compounds like ethanol, alkaloids and pesticides.
