Patent GB-190002089-A (GB)
Title: Improvements in the Treatment of Mixed Sulphide Ores containing Lead and Zinc.
Inventor: DAVIS GEORGE EDWARD
Filed: 1900-02-01
Granted: 1900-10-31
Abstract: 2089. Davis, G. E., and Davis, A. R. Feb. 1. Treating ores; silver; lead.-Mixed sulphide ores containing lead and zinc are treated, either in the lump or in a finely. divided state, with hydrochloric acid, and are at the same time heated and agitated. The solution obtained, containing chlorides of lead and zinc and free acid, is allowed to cool. If iron is present the solution is treated to oxidize the iron to the ferric state, say by adding zinc oxide and blowing in steam and air. The iron oxide is removed by settling and filtering the solution, which is then treated by the Claudet iodide process, for the recovery of any silver it may contain. After the silver iodide has been removed by settling, the solution is treated with zinc oxide and carbonic-acid gas to separate the lead as carbonate as described in Specification No. 253, A.D. 1900, [Abridgment Class Acids, alkalies, &c.]. The lead carbonate is removed by settling and filtering the solution, which is practically a solution of zinc chloride, and can be concentrated in the usual way, or can be treated with an alkali on an alkaline earth for the preparation of zinc oxide. The sulphuretted hydrogen evolved during the treatment of the ore may be used in the manufacture of sulphuric acid or in the manufacture of sulphur by the Claus method. The residue of the ore contains the bulk of the lead as chloride and may be smelted to recover the lead and any silver present, Or the lead chloride may be dissolved out by hot water. When the solution cools, the lead chloride is deposited in a form particularly adapted for use in storage batteries. Or it may be converted into carbonate by adding it along with the necessary quantity of zinc oxide to the solution undergoing the carbonic-acid treatment. Or it may be treated with milk of lime and carbonic-acid gas, to precipitate carbonate of lead, while the calcium chloride remains in solution, and can be recovered in any known way. The residue after the lead chloride is dissolved out consists mainly of gangue and undecomposed ore, and may be treated with sodium thiosulpbate for the extraction of any silver it contains. As sulphide of lead is more easily attacked by hydrochloric acid than zinc sulphide, it usually happens that if three-quarters of the loose sulphides in the mixed ore are dissolved out, the remaining fourth consists mainly of zinc sulphide. If this is separated from the lead chloride as already described, and then calcined to effect its oxidation and the removal of the sulphur, impure oxide of zinc is left, which can be used to saturate the free hydrochloric acid in the processes described.
