从含银的废催化剂中回收白银

The Recovery of Silver from Silver-bearing Waste Catalytic Agent

介绍了从含银的废催化剂中回收白银的一种新方法。采用氨浸,A还原剂还原,浸出率98.5%,还原率99.9%,直接可获高纯度的银粉,金属银纯度可达99.9%。

A new method to recover silver from silver-bearing waste catalytic agent is introduced. By ammonia leaching and reducing with reductant A, the leaching rate comes to 98.5%, reducing rate 99.9%, the fineness of recovered metallic Silver 99.9%.
