| Abstract: | Ion exchange method is one of the important technologies for abstracting metal from ore. The synthesis of a new macroporous anion exchange resin with two of weak-base functional groups for extracting gold from cyaniding pulp was presented.The effects of resin crosslinking and aminating condition on its performance for extracting gold were studied .The exchange capacity of the resin for gold was determined to be 16?mg/g dry resin and the selective coefficient for gold was 1.1. The performance of this new macroporous anion exchange resin is better then that made in Russia and can be widely used metallurgy industry. |
