摘要： The specification discloses a method for recovering non-ferrous metals such as zinc or copper iron from their concentrates, ores or any other metal containing materials into a solution containing these non-ferrous metals as sulphates and a minimal amount of dissolved iron. The resultant solution is suited without or with minimum pre-purification treatment for conventional electrowinning processes to recover such non-ferrous metals with less difficulties than the previous methods involving complex iron-removal processing. There is disclosed a method for recovering at least one non-ferrous metal soluble in sulphuric acid from a strong sulphuric acid solution containing said metal and iron as sulphates, said method comprising the following consecutive steps:subjecting said solution in a sub-divided form to thermal decomposition in a fluidized bed reactor at a temperature of from 600.degree. to 750.degree. C. with 20-150% excess air for an average retention time of 1-12 hours to obtain calcine containing ferric oxide and the sulphate of said non-ferrous metal;leaching said non-ferrous metal sulphate out from said calcine with water or dilute sulphuric acid solutions;separating said leach solution containing said non-ferrous metal sulphate from the residue; andrecovering said non-ferrous metal from said leach solution, via electrolysis or any other method.

摘要： The invention provides a cyclic process for recovering copper from sulfide ores containing copper and iron which comprises reacting the sulfide ore with sulfur dioxide gas at a temperature of at least about 500.degree. C. to form elemental sulfur, removing the elemental sulfur, reacting the residual solids with concentrated sulfuric acid at a temperature of about 180.degree. to 500.degree. C. to form copper sulfate and sulfur dioxide gas, recycling the sulfur dioxide gas for reaction with additional ore, roasting the remaining solids at a temperature of about 400.degree. C. to 900.degree. C., leaching the roasted solids with an aqueous solution to solubilize the copper sulfate and recovering copper from the solubilized copper sulfate. In another embodiment of the invention, the roasting step is eliminated by removing magnetite from the solids remaining after removal of the elemental sulfur.

摘要： Non-ferrous metal values, such as nickel, cobalt or copper, contained in oxide ores, or roasted sulfide ores, that also contain iron, are selectively reduced to the metallic state, and the selectively reduced metal values are reacted with molecular chlorine by passing gaseous chlorine through an aqueous pulp of the reduced ore to produce a pregnant solution containing the chlorinated metal values from which solution the metal values can be recovered.

摘要： A hydrometallurgical process for treating slag material, especially copper smelter slag material, comprises vigorously mixing the slag material with about one part by weight of sulfuric acid and about one part by weight of water for each part by weight of the slag material, and allowing the resulting mixture to react to produce a dry, solid material, containing the metal values of the slag in water-soluble form. These solubilized metal values may be separated by leaching from the insoluble silicious residue of the dry solid material.
