Activated Carbon Supplier

Once the carbon absorber has become loaded with gold ions it gets stripped of the gold The gold industry uses activated carbon made from the hard shell of coconuts due to its exceptional adsorption properties and inherent durability Today the gold mining industry uses activated carbon mostly in carbon-in-pulp and carbon-in-leach methods

Carbon For Gold Mining Extraction

Carbon-In-Pulp (CIP) In CIP the ore is crushed and finely ground and cyanide leached in a series of agitated tanks to solubilise the gold The granular activated carbon is added to the leached slurry where the carbon adsorbs the gold from the slurry solution and is then removed from the slurry by coarse screening

Activated Carbon Stripping

May 27 2010In many cases it isn't because the activated carbon isn't so activated (most just use it from the can and do not heat and pump on it and cool under H2) If it were a gold-cyanide complex he'd have to use very strong hot HCl to remove the bulk of the cyanide as HCN (not recommended)
