摘要
失效含银工业催化剂是一种重要的二次资源,国内每年报废含银催化剂约1000 t,可回收银约200 t。本文通过介绍失效含银工业催化剂的原料概况、回收工艺、沉淀剂选择和还原工艺,为失效含银工业催化剂回收和银冶炼生产等相关领域提供参考依据。
Spent silver-containing industrial catalysts are an important secondary resource,about 1000 tons of silver-containing catalysts are scrapped every year in China,and about 200 tons of silver can be recovered.This paper introduces the raw material overview,recovery process,precipitant selection and reduction process of spent silver-containing industrial catalysts,so as to provide a reference for the recovery of spent silver-containing industrial catalysts and silver smelting production.
