NICKEL AND COBALT ORES: FLOTATION

The usual method of nickel extraction from sulRde ores is through the production of nickel matte after enriching the nickel content of the ore. This is com-monly carried out by magnetic separation, Sotation, or a combinationof both after the ore is comminuted to below 200 m in size. The enrichment depends upon the degree of rejection of the other sulRde and non-sulRde gangue. The maximum grade ...

MURDOCH RESEARCH REPOSITORY

The choice of technology for the treatment of nickel laterite ores is generally driven by project-specific parameters, which is one reason why there are many different processing options used in currently 2 ( operating and proposed process plants. However, these processing options can be categorised under a few main "types" - smelting, high pressure acid leaching, atmospheric leaching and heap ...

Nickel / cobalt mining extraction procedures | Industrial ...

2019-09-06· At present, the large cobalt and nickel ores are in the process of clear depletion and the main ores of these two metals are constituted by minor mineral concentrations in ores formed by different metals. This requires the mineral extraction processes to be modified in each case. Thus, for “speiss” with low grade cobalt and nickel, treatment in chlorinated medium occurs: Co 2+ + Cl 2 + …

The main method for beneficiation of copper-nickel sulfide ore is flotation, while magnetic separation and gravity separation are usually auxiliary beneficiation methods. When flotation of copper sulfide nickel ores, collectors and foaming agents for flotation of copper sulfide minerals are often used. A basic principle for determining the flotation process is that it is better to allow copper ...

The HPAL Process :: Total Materia Article

As mentioned above, major reserves of nickel are contained in laterite ores, which have traditionally been treated by pyrometallurgical methods. Hydrometallurgical treatment, by direct acid leaching of the ore at temperatures above 240°C, is however an alternative treatment option for several new projects. The basic steps in the process are as follows:
