EXTRACTION OF HEAVY METALS, IRON, GOLD AND SILVER FROM SULPHATE CAKE

摘要

FIELD: metallurgy.SUBSTANCE: invention relates to hydrometallurgy and can be used for processing of concentrates, industrial products and solid wastes containing metals. Proposed process comprises leaching of cake 3 n, by HCl solution at 70°C and L:S ratio of 2. Note here that leaching is performed in the presence of table salt of concentration making at least 120-140 g/dm.EFFECT: intensified leaching, higher yield.4 tbl, 2 ex
