AEROPHINE® - 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.
