NICKEL AND COBALT ORES: FLOTATION

2016-6-7  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

60 Centuries of Copper: The Flotation Process

2021-1-21  Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways.

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
