一、吸附浸出方法的特点应用离子交换树脂从矿浆中吸附金和银,当前是通过两种方法来实现:(1)矿浆预先氰化,然后吸附;(2)与氰化浸出同时进行。第一种方法,矿浆与树脂混匀时,预先氰化的矿浆液相中的金和银被离子交换剂吸附。树脂吸附完成后进行分离,脱金矿浆送去进行除害处理,然后送入尾矿坝。应该指出,当有离子交换剂时,矿石中的金继续溶解,因此,金属的回收有所增加。如果矿石中的金溶解的较完全,而且矿石中没有氰化物的吸附剂,预先氰化在磨矿阶段就可开始,氰化钠溶液可以直
First, the characteristics of adsorption leaching method Ion exchange resin adsorption from the pulp gold and silver, the current is achieved by two methods: (1) pulp pre-cyanide, and then adsorption; (2) and cyanide leaching at the same time. In the first method, when the slurry is mixed with the resin, the gold and silver in the pre-cyanized slurry phase are adsorbed by the ion exchanger. After the resin is adsorbed, the separation is carried out, and the desmutting pulp is sent for decontamination treatment and then sent to the tailing dam. It should be noted that in the presence of ion exchangers, the gold in the ore continues to dissolve, and as a result, metal recovery increases. If the gold in the ore is more completely dissolved and there is no adsorbent for the cyanide in the ore, precylation can begin at the grinding stage and the sodium cyanide solution can be straight
