When floatability difference happens to the various nickel elements in the raw ore, the nickel ore can be recycled from tailings after the copper and nickel did the mixing flotation. Copper- Nickel Ore Flotation Process: A basic principle of copper-sulfide nickel ore process is that it is better to let the coppers assimilate into the nickel ore.

Sensor-based automatic ore sorting technologies are used in the minerals industries to efficiently remove waste and sub-marginal grade material from crushed and screened run of mine (ROM) ore, producing a coarse (typically >10 mm) upgraded pre-concentrate at an early stage in the mineral processing circuit.
The trajectory of the ore as it leaves the conveyor belt will determine where in the bin or pile each size of the crushed ore will land. Once in the bin, another stage of classification takes place. The smaller ore due to its lesser size and weight, tends to filter downwards faster than the coarse material does.
Conventional crushing, grinding, flotation, and pressing are used to process run-of-mine ore into separate nickel and copper concentrates. Road haul trucks arrive at the mill and dump their load in the enclosed Coarse Ore …
