- process nickel ore
The separation process for nickel is highly dependent upon the type of ore. Nickel sulfides, such as those found in the Canadian Shield and Siberia, are generally found deep underground, making them labor-intensive and expensive to extract. However, the separation process for these ores is much cheaper than for the lateritic variety, such as ...

Afterwards, the crushed ore undergoes a flotation process, a method used to separate and concentrate ores based on whether their surfaces are repelled by, or attracted to, water. It is one of the most widely used processes for extracting minerals like nickel from their ore – the natural rock or sediment that contains them.

The result showed that inner and outer coal in the carbothermic reduction process of laterite nickel ore can affect the selectivity performance of nickel. The best nickel recovery (93%) was obtained when using 70% inner coal and 30% outer coal. On the other hand, the best nickel content (13.99%) was achieved when using 90% inner coal …

The process of reductive roasting followed by acid leaching is similar to that of reductive roasting-ammonia leaching process, in which nickel and cobalt in laterite ore are selectively reduced to the metallic state by reduction, and hematite is reduced to magnetite and wüstite [63, 64]. Nickel and cobalt in the metallic state are easily ...

Primary world nickel production in 2020 was 2430.7 kt Ni; 69% (1677.7 kt) of them came from oxidized nickel ores (laterites) and 31% from sulfides. Production-wise, 87.7% of the 1677.7 kt came from pyrometallurgical and 12.3% from hydrometallurgical processes. For a long time, Fe-Ni had a 20–40% Ni analysis, but in 2006 a new Fe-Ni quality came into …

On top of that, with nickel being one of the most technically challenging metals to process and refine, and every operation being unique, further challenges will also be asset dependent (Exhibit 1). For miners, the type of ore deposit—sulfide or oxide (or laterite, further subdivided into saprolites and limonites)—defines the whole value chain.
