The easiest method for achieving this is by gravity separation. This relies on the difference
The gold CIP (Carbon-in-Pulp) processing is widely used to extract gold from ore. It mainly involves using activated carbon to adsorb gold from a cyanide solution, then eluting and regenerating the carbon for reuse. It is mainly suitable for beneficiating gold-containing oxidized ore with high slime content and containing carbon ore.
