从废银/沸石催化剂中回收银

To recover silver from waste silver catalyst carried in zeolite

本文简要地介绍从以沸石为载体的废银催化剂中回收银的各种方法及其优缺点。并用正交法对纯碱—硼砂—萤石熔炼法进行了配料试验,取得了良好的技术经济指标。同时还对熔剂:纯碱、硼砂、萤石的作用进行了理论探讨。因而本文对金银其它原料之熔炼,亦有参考价值。

This paper described the various methods and their strong and weak points to recover silver from waste silver catalyst carried in zeolite. A synthetical testing was made to define the ingredient of fluxing agents, soda ash, borax and fluorbaryt for smelting waste silver catalyst. The function of these agent were investigated theoretically,thus,this paper can be the reference for smelting gold, silver and other metals.
