Copper Sulphide Mineral

Sulfide in the mineral is oxidised to sulfate without the generation of SO 2 or H 2 S. The best selective recovery of copper (99 at%) from chalcopyrite was obtained with a mixed DES of 20 wt% choline chloride-oxalic acid and 80 wt% choline chloride-ethylene glycol.

  • Main Copper Sulphide Extraction Process | Mining Pedia Main Copper Sulphide Extraction Process | Mining Pedia

    Dec 21, 2019 Copper sulfide ore has better floatability than sphalerite, pyrite and another sulphide, so it is more likely to float from the pulp by adsorpting collector. Therefore, froth flotation process is the main mineral process method used for the extraction of copper from copper sulphide.
