However, because the rich ore con tains more copper, it requires less of these inputs per tonne of copper recovered. The gross ton nage basis for costs is particularly important in

Abstract The leaching of dolomitic copper ore using sulphuric acid under controlled conditions was studied with a view to evaluating the economic value and the effect of ore pulverisation, particle size, temperature and pH on the recovery of copper from chalcopyrite. The samples were ground and mixed with water and sulphuric acid to form an acid

Therefore, when creating a mining plan in ac cordance with a production plan, it is necessary to plan for both ores containing a low copper content and a higher copper content.
