Traditionally, activated carbon is used for gold extraction. The precious gold will be adsorbed on the surface by activated carbon, and then recovered by washing or direct incineration. The use of ion exchange resins for gold extraction has many advantages over activated carbon, because through the special production processes, we can place selective ions on the effective functional groups on its structure to selectively adsorb precious metal. Therefore, due to the advantages of economic considerations, ion exchange resins are commonly used for precious metal recovery. Most of them use anion exchange resin to exchange and adsorb precious metals.
Whether strong basic resin, weak basic resin or bifunctional resin containing strong base and weak base, when they adsorb gold from the cyanide medium, they are all carried out in a typical ion exchange reaction.
Lanlang ® TA301GD Is a premium grade macroporous weak base anion gold extraction resin with polystyrene matrix and tertiary amine (Dimethylamine) function group. It is mainly used to absorb and recover gold in the solution and waste water that contains gold.
It has the advantages of high exchange capacity, low leakage, strong selectivity, etc.
