The beneficiation process of nickel ore,copper-nickel …

 · A basic principle for determining the flotation process is that it is better to allow copper to enter the nickel concentrate, and to avoid nickel entering the copper concentrate as much as possible. Because the nickel in the copper concentrate is lost during the smelting process, the copper in the nickel concentrate can be completely recovered.

AEROPHINE®

In sequential flotation, pH is raised to pH 11 with lime and a starvation dosage (6 g/t – 15 g/t) of AEROPHINE Ⓡ 3418A promoter is used. This allows selective flotation of a high grade copper concentrate with minimal nickel content. Slurry pH is then reduced to about pH 9 and a nickel concentrate is produced.
