【摘要】 研究了赤泥酸浸条件,水解法制取钛白,溶剂萃取法富集钪,水解制取铁红等工艺条件和流程.赤泥先用盐酸浸出,浸出液回收绝大部分的钪、铁和铝;浸出后的残渣用浓硫酸分解,酸解液回收钛及其余部分的钪.更多还原

【Abstract】 The paper studied the conditions of red mud’s leaching,and discussed the processing of Titanium white’ s extraction with hydrolysis.After Titanium white’ s leaching in Hydrochloric acid,leaching liquids can retrieve most of Sc,Fe and Al.更多还原
