It is found that the maximum separation coefficient of nickel and cobalt is 1.2 × 10 4 at the extraction ratio of 1:1. Under this extraction ratio, the more extraction amount of cobalt, the less extraction amount of nickel. It realizes the effective separation of nickel and cobalt. Therefore, the best extraction phase ratio is regarded as 1:1.

In conventional processing of mixed sulfide ores of copper and nickel, the separation of copper from nickel begins in the ore beneficiation plant. Although copper and nickel are mutually soluble in the metallic state, in sulfide ores they occur as distinct minerals, usually chalcopyrite (CuFeS2) and pentlandite (FeNi)8S4).

excellent cobalt-nickel separation primary leach liquor by Cyanex 272. However, manganese extraction from the leach liquor along with cobalt could not be avoided, thus increasing the cost of the process. For sulphide ores, there is another alternative; if the ore can be concentrated by flotation, matte smelting is used instead of leaching.

In the current work, nickel was upgraded in ore I (sample from the intermediate zone between saprolite and limonite) from 1.1% to 1.5% at 70% recovery. It should be noted that ore I has the highest amount of quartz among the tested samples (Table 1). This should have helped upgrading nickel in this ore using gravity separation.
