The study evaluated the milling kinetics of three copper ores, from a multimineralised deposit, which were identified as sulphide 1 (with bornite as a dominant copper mineral), sulphide 2 (mainly composed of chalcopyrite) and oxide (with malachite as a dominant copper mineral) and related the breakage parameters to the mineral composition data. Five monosize fractions between 1000 µm and ...

Size reduction is a necessary operation in mineral processing plants and provides the desired size for separation operations and the liberation of the valuable minerals present in ores. Estimations on energy consumption indicate that milling consumes more than 50 % of the total energy used in mining operations. Despite the fact that ball milling is an efficient operation, it is energy ...

In general, only the dissociation of the sulfide ore monomer is required for gold encapsulated in sulfide minerals. However, for the gold that is continuous with the gangue, the grinding fineness needs to reach the dissociation of the gold monomer.
