Abstract: Copper metal is produced from copper containing ammonia - ammonium chloride liquor by precipitating copper containing crystals which are subsequently reduced to copper metal using hydrogen containing gas with the source of the copper in the ammonia ammonium chloride being leaching of copper containing ores and/or wastes and/or residues.

Abstract: The present invention relates to a novel approach to the use of gas bubble hydrophobic particle aggregates to give improved separation and recovery of valuable minerals from a wide range of ore types. A process for formation of gas bubble particle aggregates within a slurry and separating the formed aggregates from the slurry including using first and second flotation cells wherein the first and second cells operate with different levels of shear and including transfer of externally formed gas bubble hydrophobic particle aggregates to either or both of the first and second cells.
