摘要
用地下天然碱对硫酸生产废钒催化剂进行直接浸取 ,得到 ρ(V2 O5)为 1 5～ 1 6kg/m3的含钒溶液 ;用离子交换法对浸出液进行净化处理 ,然后沉钒、脱氨 ,得到w(V2 O5) 99 5%的产品。钒收率达到 85%。
Vanadium pentoxide is recovered from waste vanadium catalyst of sulphuric acid plant by a process consisting of leaching with underground natural alkalis to obtain solution containing V 2O 5 15～16?kg/m 3, purification by ion exchange method, deposition and ammonia removal The purity of product vanadium pentoxide is up to 99 5% with vanadium yield of 85% 〔
