摘要： The invention provides a method for selectively solubilizing the non-ferrous metals contained in sulphurized ores and concentrates, with regard to the iron and sulphur therein, by subjecting the ore or concentrate to lixiviation with an aqueous solution of cupric chloride at a temperature above 50.degree. C., preferably at a temperature between 70.degree. C. and 105.degree. C., and then regenerating said aqueous solution in situ at atmospheric pressure by means of air and a regeneration agent selected from the group consisting of hydrochloric acid and ferrous chloride. The invention also contemplates the preferable inclusion in the aqueous cupric chloride solution of an agent for solubilizing cuprous chloride selected from the group consisting of an alkali metal chloride, an alkaline earth metal chloride, ammonium chloride, and ferrous chloride. When the regeneration agent is hydrochloric acid, the pH of the aqueous cupric chloride solution is at most 1 in the presence of ferrous chloride and at most 3 in the absence of ferrous chloride. When the regeneration agent is ferrous chloride, the pH of the aqueous cupric chloride solution ranges between 1 and 3, the temperature of the solution exceeds 50.degree. C., and the solution contains at least 1g/l of cuprous ions and at least 2g/l of ferrous ions, with the result that geothite is precipitated and may be separated, and the non-ferrous metals isolated as the aqueous solutions of the metal chlorides.

摘要： A metal is leached from an ore or concentrate with an aqueous solution of an organic chelating agent. In selecting a suitable agent the formula Beta >10 3/Ksp is employed wherein Beta is the stability constant of the chelate composed of the agent and the metal to be leached, and Ksp is the solubility product constant, in water, of the compound in the ore or concentrate which supplies the metal in the chelate. As an example, an aqueous solution of EDTA leaches copper from a carbonate ore in a limestone matrix. Metal values are then recovered from solution by chemical reduction, electrolysis, cementation, sulfide precipitation or pH control.

摘要： THE BENEFICIATION ACCORDING TO THE PRESENT INVENTION IS CARRIED OUT BY COMMINUTING THE STARTING COMPLEX SULFIDE ORE (INCLUDING SO-CALLED BLACK ORE), WHILE BEING CONCURRENTLY AIR-DRIED, THE COMMINUTED DRY ORE IS THEN FORTHWITH PULPED, AND THE PULP IS SUBJECTED TO LEACHING WITH E.G. WATER TO LEACH OUT WATER-SOLUBLE CONSTITUENTS THEREFROM. FILTRATION SEPARATES THE WATER-INSOLUBLES FROM THE FILTRATE. ROUGH FLOTATION SEPARATES THE FILTER CAKE INTO A PYRITE CONCENTRATE AND A COPPER AND ZINC CONCENTRATE. THE LATTER IS SEPARATED INTO A COPPER CONCENTRATE AND A ZINC CONCENTRATE BY DIFFERENTIAL FLOTATION, FOLLOWING CONDITIONING. CYANIDE SOLUBLES ARE REMOVED FROM THE ZINC CONCENTRATE. WASH WATERS AND FILTRATES FROM THE LEACHINGS ARE RECIRCULATED AND RE-USED.
