Procedure

U.S. Pat. No. 1,799,166 provides for treatment of zinc-bearing material with acid to convert water insoluble compounds of magnesium and calcium into relatively water soluble compounds. Sulphuric acid may be used to form magnesium sulphate and calcium sulphate. Although soluble magnesium sulphate is removed readily in a solids- liquid separation, repeated washings with water are needed to separate particles of calcium sulphate, which are only slightly soluble, from solids containing the zinc-bearing material.
