steps of extraction of gypsum from chalcopyrite
Hydrometallurgical Process an overview | ScienceDirect
Ammonia leaching was based on the extraction of easy to leach copper from chalcocite and bornite (70–80% of copper), extraction of chalcopyrite (and the majority of gold and silver) from the leaching residue by flotation for processing in the smelting plant, with the removal of pyrite, containing almost 70% of the sulphur of the original concentrate.

Solvometallurgical process for extraction of copper from
Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).
