为了有效地从活性炭上回收贵金属,就需要从吸附剂上完全分离已吸附的贵金属矿物组分,并使活性炭能恢复其原有的吸附容量。 参考文献中指出,使用过量的络合剂溶液能相当有效地从活性炭上回收已吸附的银。采用这一方法的前提是必须制定出对被活性炭从氰化溶液中吸附的金、银进行解吸的最佳制度。
In order to effectively recover the precious metal from the activated carbon, it is necessary to completely separate the adsorbed precious metal mineral component from the adsorbent and allow the activated carbon to recover its original adsorption capacity. It is pointed out in the reference that the use of an excess of complexing agent solution can quite efficiently recover the adsorbed silver from the activated carbon. The premise of this approach is that it is necessary to devise an optimum system for the desorption of gold and silver adsorbed from the cyanide solution by activated carbon.
