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 …

Media Attributions; Metal deposits are mined in a variety of different ways depending on their depth, shape, size and grade. Relatively large deposits that are quite close to surface and somewhat regular in shape are mined using open-pit mine methods (Figure 8.1.5 in Section 8.1).Creating a giant hole in the ground is generally cheaper than making an …

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.
