【Abstract】 This article deals with the technological process of making zinc sulfate from smithsonite.The problem of removing magnesium is solved by using different solubility,so the content of seven-water zinc sulfate reaches the standard of exportation(≥98 %).Compared with producing seven-water zinc sulfate by using zinc dust and zinc dregs,the cost of product is greatly decreased.更多还原
