用含钴废催化剂制取氯化钴和氧化铁红

Preparation of Cobalt Chloride and Iron Oxide Red Using Spent Cobalt-containing Catalyst

研究了采用化学分离法从含钴废催化剂中回收氯化钴及氧化铁红。试验结果表明:所得氯化钴(CoCl2.6H2O)的纯度≥96%,钴回收率≥84%;氧化铁红(Fe2O3)纯度≥65%,铁回收率≥88%;试验工艺可行,经济效益明显。

Recovery of cobalt chloride and iron oxide red from spent cobalt-containing catalyst using chemical seperation method is researched.The results show that purity of cobalt chloride（CoCl2·6H2O） is more than 96%,and recovery rate is more than 84%;purity of iron oxide red is more than 65%,and recovery rate of iron is more than 88%;the process is feasible and has cosiderable economic benefits.
