Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron
To explore the possibilities, flotation with various dosages of copper addition was investigated for this ore with specific interest in how the nickel recovery
Historically, selective flotation of copper from nickel sulfides has been achieved through pH modification; however, this method is rarely efficient, resulting in
