摘要
利用湿法提钒采用食盐代替部分纯碱从熔化渣(攀枝花铁精矿竖炉还原熔化分离的钒钛渣)中提钒。取得了阶段性效果。实验结果表明:转浸率中达到83 73%～88 99%。操作条件是:氯化钠∶碳酸钠∶熔化渣=10∶15∶10 0。焙烧温度在70 0℃恒温1h。95 0℃恒温2h。浸取温度为80℃左右,浸取时间为1h。
Vanadium was extracted from melthed residue by means of leaching method replacing part pure alkali with salt. The optimum operation conditions were determined and the leaching diversion rate was up from 83.72% to 88.99%
