Applications | Solvay

Sequential Copper-Nickel Flotation. 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.

AERO® NP21 Promoter | Solvay

This product is a highly versatile collector that is most often used as a secondary collector in bulk copper-nickel flotation or for selective copper flotation in copper-nickel sequential flotation. It can also be used to enhance discrimination against nickel and iron sulfides in copper-nickel separation stages.
