Abstract
309,268. Levy, S. I., and Gray, G. W. Feb. 10, 1928. Ferrous and zinc chlorides.-Ferrous chloride crystals are deposited from solutions, such as those obtained by heating pyrites in absence of air and treating the residue with hydrochloric acid, by saturating the solution with hydrochloric acid gas. The mother liquor may be used to react hot with fresh materials containing iron. Alternatively a ferrous chloride solution may be caused to absorb hydrochloric acid gas and to react hot with materials containing iron until the liquor contains 90 per cent ferrous chloride at 100‹ C., whereupon, after filtering, the solution is cooled to separate the ferrous chloride. Lead, if present, is removed by electrolysis, and when zinc is present the cycle of separating ferrous chloride and bringing more iron into solution is repeated until the zinc concentration is, say, 80-100 grms. per litre, wherafter the zinc-rich solution is treated by concentration or saturation with hydrochloric acid gas to remove the bulk of the remaining ferrous chloride before recovering the zinc. The gaseous hydrochloric acid used in the process may be obtained from the ferrous chloride crystals in the manner described in Specification 307,188.
