copper nickel bulk flotation

The laboratoryflotationtestwork program was focused on determining whether a satisfactorybulk flotationconcentrate could be produced which subsequently could be taken tocopper/nickelseparation in order to produce marketable concentrate products (Ni>10%; Cu>25%). Based on positive current test results the next phase of testwork has been

    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

    The plant will use a bulk flotation circuit designed to produce separate copper and nickel concentrates. The circuit will feature bulk rougher flotation, regrinding, a two-stage bulk cleaning process, followed by copper and nickel separation. The sulphide ore will be divided into two types, namely pyrite-violarite (PV) and non-PV
