• Nickel, nickel carbonyl, and some nickel compounds (HSG .

    Nickel ore deposits are accumulations of nickel sulfide minerals (mostly pentlandite) and laterites. Nickel is extracted from the mined ore by pyro and hydrometallurgical refining processes. Global mining production of nickel was approximately 67 million kg in 1985. Most of the nickel is used for the production of stainless steel and other ...

  • What Objects Are Made Out of Nickel? | Sciencing

    Stronger than pure nickel, nickelcopper alloys comprise a minimum of 63 percent nickel and 28 to 34 percent copper. These alloys also contain at a maximum 2 percent manganese and percent iron, and are widely used in oil refineries. They also have many marinerelated uses where durable, corrosionresistant products are required. Because this alloy is a heat conductor, it's often used ...

    In this paper, a systematic thermodynamic analysis of carbothermic reduction of saprolitic nickel laterite ore was carried out. Different carbon sources—such as pure C, subbituminous, and lignite—were used for the carbothermic reduction at 1000 °C (1273 K). The effect of the different additives—such as S, FeS, Na2S, Na2SO4, and CaSO4mdash;was also systematically evaluated.

  • Specific Gravity Determination

    Apparent specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance. The reference substance is nearly always water at its densest (4°C) for liquids; for gases it is air at room temperature (21°C). Nonetheless, the temperature and pressure must be specified for both the ...
