    摘要： Provided is a method of recovering copper and one or more precious metals comprising leaching copper-bearing ore and/or concentrate under atmospheric or slightly pressurized conditions at a temperature below the boiling point of the leach solution in a sulfuric acidic solution in the presence of one or more alkali metal or alkali earth metal halides, whereby the total halide concentration is from 30 to 115 g/L, to dissolve copper and to obtain a leaching liquor comprising copper, sulfur species, and halides in solution. The leaching liquor is then subjected to a solid-liquid separation after which a first aqueous pregnant leach solution and a copper depleted leaching residue are obtained. Copper is purified by solvent extraction from the first aqueous pregnant leach solution to obtain a first copper-containing loaded organic solution and a first aqueous raffinate. The copper containing loaded organic solution is stripped and copper is recovered.

    摘要： A highly photosensitive element made from fine particles of highly purified copper halide is described. These purified particles may be made by ball-milling an aqueous slurry of relatively insoluble copper halide and then decanting and washing said particles, or be dissolution in an acidic solution of acetonitrile and recovering the particles of pure copper halide therefrom. Elements made using the material of this invention are suitable for the preparation of printed circuits, for example.
