Copper-Nickel ores - Danafloat

Some plants use bulk flotation in an acid pH environment which is achieved using SO2 or H2SO4. Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails.

NICKEL AND COBALT ORES: FLOTATION

A typical example of a nickel sulRde plant operat-ing with highly Soatable talcose gangue is at Trojan mineinZimbabwe.TheZimbabweansulRdedeposits contain very low grades of nickel (0.6%) and copper (0.04}0.4%). The easily Soatable non-sulRde min-erals dilute the grade of the concentrate and also result in nickel losses into the tailings. This ...

Smelting of Nickel-Copper and Nickel Sulfide

Copper-nickel ore flotation has the following four basic processes. 1) Direct priority flotation or partial priority flotation process: When the copper content in ore is much higher than that in nickel, this process can be used to separate copper into a separate concentrate. The advantage of this process is that the copper concentrate with ...
