The main beneficiation method of copper ores is flotation, in some cases the gravity separation and magnetic separation are applied. Generally, copper sulfide ore, mixed copper ore and copper oxide ore are processed by flotation method. For the refractory mixed copper ore and refractory copper oxide ore, hydrometallurgy or combined hydrometallurgy and flotation are adopted.

Through the automatic control system, the whole process of ore beneficiation is under monitoring, so the production line can be large-scale, automatic and easy to manage and control.

Copper ore processing can be applied to all kinds of copper sulfide ores, as well as most mixed copper ores and copper oxide ores. It has significant separation effect for chalcopyrite, copper molybdenum ores and porphyry copper ores.

The principle of more crushing and less grinding is achieved：

1. the ore particle size is crushed to 10-12mm or less by three-stage-crushing with single closed circuit stage process to reduce the load of the grinding system
2. Use New flotation reagents：the flotation results can be greatly improved by using compound collectors instead of traditional xanthate collector;
3. Pneumatic flotation machine is used to ensure the flotation effect：Pneumatic flotation machine is adopted to obtain good ore beneficiation indicators;
4. High degree of automation：through the automatic control system, the whole process of ore beneficiation is under monitoring, so the production line can be large-scale, automatic and easy to manage and control.

TOMINE usually applying multi-stage grinding process to protect graphite flake from damaged. Applying multiple grinding and separation to meet the customers needs. Hydrocyclone can be used at the thickening stage, which keep the grinding density at 40% to 50% for better grinding efficiency. At the multi-flotation stage, No.2 oil, No.4 oil, ether glycol and butyl ether oil are the common foaming agents. As for collectors, mainly use kerosene, diesel oil, heavy oil, fat sulfonic acid ester, acid,etc. For graphite ore accompanied with heavy minerals, we usually adopt the process of mixing gravity separation and flotation. That is, separate the heavy minerals with gravity separation then process the heavy separation tailings with flotation method.
