Nickel is commonly present in two principal ore types—sulfide or laterite. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt (Co), and often precious metals such as gold (Au) or platinum (Pt), palladium (Pd) and rhodium (Rh) (the platinum group metals or PGMs) …

The conventional nickel smelting and refining is the dominant strategy for nickel production from the sulfide nickel ores. The main disadvantages are the significant amount of SO 2 emissions during smelting and complex refining processes. In this paper, the authors investigated a solid-state nickel extraction method that recovered nickel …

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.

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. At the end of the flotation process, the nickel sulphides can be skimmed off and dried. Now at around 18% nickel, the concentrate is driven to Deception Bay, around 100km north of the mine.

The sulfating roasting process of nickel sulfide ore is essentially a process of selective oxidation of metals in minerals. In this process, air or oxygen-enriched air is generally used as oxidant, and a multiphase reaction takes place between solid phase and gas phase. After roasting, valuable metals such as nickel, cobalt, and copper are ...
