Copper industrial minerals include: natural copper, chalcopyrite, chalcocite, tetrahedrite, azurite, malachite, etc. Chalcopyrite (a compound of copper, sulfur, and iron) is mined mainly, followed by chalcocite and bornite. If copper ore wants to be fully utilized, it must be processed by flotation. Flotation separation is an important copper ore …

11.5.3.1 Beneficiation. Mineral beneficiation begins with crushing and grinding of mined ore for near-complete separation of ore and gangue minerals as well as between ore minerals. Each processing step is designed to increase the grade (concentration) of the valuable components of the original ore.

Fine gangue material or iron ore slimes having <45%–55% Fe are discarded as reject during the ore beneficiation process. Aiming towards the good quality (>60% Fe) ore and its non-renewable nature, the mineral rich ore is depleting, and the slimes are increasing at a rate of ∼11–13% for the hematite reserves in India, as reported by the ...

This is equivalent to about 2 billion tonnes and 1 billion tonnes iron ore, respectively. The incremental iron ore demand of about 440 mt from increased DRI production could be met, assuming adequate replacement of depleted reserves. However, from the qualitative perspective, there is a potentially serious problem. This is the iron ore challenge!
