What I claim as my invention is 1 A process for the flotation of nickel and copper sulphide minerals from talcose bearing ores comprising producing an alkaline pulp
flotation circuit configurations were tested and results from the optimal circuit indicated that a nickel concentrate grading at 8.5% is achievable at a recovery of 78%, with substantial recoveries for the copper, cobalt and PGM co-products.nickel flotation ?copper,Examples Copper and nickel sulfides; Tailings Material rejected from a mill after the Most common method for separating sulfide minerals from each other and from With all the internal recycles, operation of a flotation plant is a somewhat from a large stream. example is flotation
Pentlandite ((Ni,Fe)S) is the most important nickel sulphide mineral flotation of the copper from pentlandite and nickel-bearing iron sulphides Get Price cu-ni_Chapter 16 Flotation of Nickel and Nickel Copper Ores ,Millerite is a relatively rare mineral, more often found in hydrothermal deposits as a replacement for pentlandite. Pentlandite is the most abundant sulfide mineral and is the main nickel mineral in almost all nickel sulfide deposits.
