The usual method of nickel extraction from sul Rde ores is through the production of nickel matte after enriching the nickel content of the ore. This is com-monly carried out by magnetic separation, Sotation, or a combination of both after the ore is comminuted to below 200 m in size.

The flotation process utilizes the surface properties of different minerals to induce selective separation. The surface energy of mineral particles will dictate whether they are concentrated in the mineral-rich froth phase or left in the gangue-rich tailings. ... For example, the Esan-Balya Sulfide Mine processing a Pb-Zn-Fe sulphide ore the ...

It is widely accepted that flotation is the most popular mineral processing method consuming the greatest amount of water in all the mineral processing plants, e.g., floating 1 t ore normally requires 3~7 t water. Therefore, the flotation process can be regarded as the most intensive water consumption section in a mineral processing circuit.
