Abstract

4706. Cunnington, A. V. Feb. 25. Zinc.-To obtain zinc in solution from blende, calamine, zinciferous pyrites, &c., the ore is, in most cases, calcined, and preferably reduced to powder. If much iron is present, it is partially reduced by producer gas or otherwise after roasting. The powder is introduced into a strong solution of zinc chloride, sufficient hydrochloric acid being added continuously or from time to time to keep the solution about neutral. The acid is introduced below the surface of the liquid in the dissolving-chamber to prevent acid fumes from being emitted. The liquid is well stirred during the process. In some cases, hydrochloric acid gas is condensed in a solution of zinc chloride, the liquid being added to the leach during the operation, or the hydrochloric acid gas may be led into the solution itself during the addition of the ore. The solution is allowed to settle, and is filtered, and afterwards purified by the removal of lead, copper, cadmium, &c., by electrolytic or chemical methods. The arsenic is removed by the addition to the neutral or alkaline liquor of freshly - precipitated ferric hydroxide ; or the hydroxide may be formed in the liquid by the addition of a ferric salt and zinc oxide, lime, or the like. Instead of hydrochloric, sulphuric or other acid may be added with the powdered ore, the corresponding zinc salt being used as the solvent. The zinc solution, after purification, may be evaporated, or at once electrolyzed to obtain the zinc.
