Two broad ore types. Nickel occurs in two broad ore types: laterite (oxide) ores, principally located in tropical and sub-tropical areas, and; sulfide ores, principally located in the temperate to sub-Arctic regions. Major nickel mining locations are depicted in the map – but some of these locations have many operations, and some only one.

Selection Of Nickel Ore Beneficiation Process & Equipment
Nickel ore mainly includes sulfide copper-nickel ore and nickel oxide ore (latterite nickel ore). The beneficiation and processing methods of the two are quite different: different beneficiation methods are selected according to the grade of nickel sulfide ore, and then nickel is prepared in different ways; the smelting methods of nickel oxide ore are generally divided into …
