Activated carbon is an essential tool in the gold mining industry. With the help of cyanide, activated carbon extracts gold. Gold gets broken down with a cyanide solution, and the ions then get exposed to GAC absorbers. The GAC pores concentrate the gold complex.Online Chat
In gold extraction a carbon with a high micropore distribution would facilitate effective and efficient adsorption of gold-cyanide complexes. If you are targeting removal of large colored molecules and contaminant species, a carbon with greater distribution of meso and macro pores would be suitable.Online Chat

Nov 02, 2018 The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks or reaction vessel so that leaching and adsorption take place in the same tanks.Online Chat
When used alone, BC-Carbon can remove up to 90 of the fluoride in water. The efficiency of bone char can be improved by adding pre-filters that remove heavy metals and other contaminants before exposure to the BC-carbon. Bone char works best at a slightly acidic pH and may not work as well with hard water.Online Chat
A process is disclosed which is directed to recovering gold andor silver values from activated carbon, wherein gold andor silver has been adsorbed thereon.
