Abstract
A purification method of zinc sulfate leachate is provided. The purification method of zinc sulfate leachate comprises contacting the zinc sulfate leachate with a zinc powder under a non-oxidizing atmosphere to form solution containing a precipitate of impurity metal; and removing the precipitate of impurity metal from the solution and getting a purified zinc sulfate leachate. A purified zinc sulfate leachate may be prepared with a higher purification efficiency and a lower energy consumption than prior art.
