低铜高铁高酸溶液萃取性能研究
|
摘要
对Lix984H在高酸高铁溶液中的萃取性能进行试验研究和工业验证。结果表明,增大溶液中的铜浓度、加大铜铁比例、降低溶液的酸度、适当增大相比和控制萃取率,有助于提高萃取过程的铜铁选择性,降低试剂单耗。
Extraction performance of Lix984 Hin high acid high iron solution was experimentally studied and industrially verified.The results show that selectivity of copper and iron during extraction process can be improved and reagent consumption can be reduced by increasing copper concentration in solution and proportion of copper and iron,reducing acidity of solution,and appropriately increasing phase ratio and control extraction rate.
