No. 12194.—23rd November, 1899.—JAMES GITSHAM, of 445, Punt Road, Richmond, Victoria, Metallurgist. Improved method or process for the extraction and recovery of zinc from sulphide ores.

Claims.—(1.) My described process for the extraction and recovery of zinc from sulphide ores consisting essentially in pulverising and roasting the ore at a temperature insufficient to volatilise the zinc contained therein, adding metallic zinc thereto, leaching firstly with water and afterwards with one or more weak solutions of sulphuric acid, applying steam into such solutions to increase the temperature of and agitate same, and, lastly, the application of an alkali to produce neutralisation of the acid and precipitate the zinc contents from the solution, substantially as and for the purposes set forth. (2.) My described method or process consisting in first pulverising, and secondly roasting, the ore at a temperature of about 600° Fahr.; thirdly, adding powdered metallic zinc in the proportion of 1 per cent. by weight to the ore; fourthly, by leaching such mixture with water; fifthly, by leaching the mixture with one or more solutions composed of from 2 per cent. to 10 per cent. of sulphuric acid by weight with water; sixthly, applying steam to the solutions so as to raise them to a heat not exceeding 200° Fahr., and to agitate them; seventhly, by the application of sodium or analogous alkali in sufficient quantity to the acid solution to neutralise same, and to cause precipitation of the zinc from the solution, and removing the precipitate from the solution, substantially as and for the purposes set forth. (3.) In the method or process as claimed in claims 1 and 2, the cyclic operation of the solution, with or without the fortification, from the first to the last step, twice or oftener, until such solutions become sufficiently charged with zinc to economically justify neutralisation by an alkali.
