The process begins by adding the sulfideassociated mineral to a reactor with sulfuric acid and pressurised air. This procedure removes the sulphides to obtain nickel
Nickel (element #28, symbol Ni) is a silvery shiny, metallic element. It can be hammered into thin sheets, which means it is malleable. Nickel was discovered in
Nickel. Nickel is a silver metal with a slight golden tinge with the symbol Ni and is atomic number 28. Nickel occurs mostly in combination with sulfur and iron. The commodity

With the vigorously growing demand of the steel industry, corrosion resistance alloys, clean energy industries, and a variety of engineered infrastructure or technology, highgrade nickel ores are being exhausted gradually in the world. This review outlines metallurgical processes for nickel production from various nickel sulfide ores
The ore sample contains 1.32% Ni, 10.79% SiO2, 78.39% Fe2O3, 1.3 g/t Ag, and 1.0 g/t Au. The ore sample is constituted of about 70% magnetite, 15% sulphide minerals, and 5% chromite and iron
nickel. Process gases are cooled, and particulates are then removed by gascleaning devices. Nickel Refining Various processes are used to refine nickel matte. Fluid bed roasting and chlorinehydrogen reduction produce highgrade nickel oxides (more than 95% nickel). Vapor processes such as the carbonyl process can be used to produce highpurity
The large potential of nickel causes many mining companies to apply for mining . licences. As of July 31, 2013, the North Morowali Regency Government has issued 52 Mining Business License (MBL) for Nickel Minerals. A total of 52 MBLs, 28 MBLs with an area of 135,991 Ha are exploration status, while status is a Licence given by local
The process begins by adding the sulfideassociated mineral to a reactor with sulfuric acid and pressurised air. This procedure removes the sulphides to obtain nickel (II) sulfate and cobalt (II) sulfate in solution. In this first dissolution stage, the sulfide is removed. NiS + 2O2 NiSO4. CoS + 2O2 CoSO4.
A generic flow sheet for the recovery of cobalt from copper/nickel mines is shown in Figure 3. Laterite ores are currently primarily being treated using highpressure acid leaching (HPAL). HPAL is
At present, the primary feed to the refinery is a highgrade nickel cobalt sulfide from Moa, Cuba. A flow diagram of the Sherritt process is shown in Fig. 5. The Sherritt process is adaptable to handle a wide variety of different feedstocks. It has been adopted by Western Mining Corporation in a refinery at Kwinana, Western Australia.

The development of the nickel purification and recovery flow sheet for the Mesaba concentrate was divided into six distinct stages, with each stage having its own objective. A brief description of each stage is presented in Table 2. Table 2: Mesaba Nickel Flow Sheet Development Project Stage Project Description Objective
The nickel and cobalt are separately reduced to metal products. The flowsheet below shows the unit operations used in the process. Source: Acid Leach ProcessMETMOC; NickelProcess; The main source of the world's nickel is from coppernickel sulphide ores with those mined at Sudbury, Ontario being by far the most extensive.
Nickelcadmium rechargeable batteries are used to power mobile phones, radios, clocks and calculators. Coins: Nickel was first used for coinage in Belgium in 1860, and has been widely used since then.
