ABSTRACT:
The invention relates to a method of winning copper and accompanying metals from sulfidic ores, post-flotation deposits and waste products in the pyrometallurgical processing of copper ores.
In accordance with the present invention, transferring of insoluble minerals of the metals into solution consists in leaching the above materials, initially ground to below 0.1 mm particle size, by means of a mixture of a heterocyclic aromatic amine, selected from the group consisting of pyridine, .alpha.-picoline, .beta.-picoline, .gamma.-picoline and 2,6-lutidine with a chlorinated methane derivative selected from the group consisting of methyl chloride, methylene dichloride, chloroform and carbon tetrachloride. The liquid phase being separated from the solid residue, the metal compounds are separated from the solution and depositing by known methods, e.g. by electrodeposition. The leaching process is preferably performed at the boiling temperature of the solvent mixture, the solvents being recycled to the process, preferably after purification by known methods.
