FERRONICKEL PRODUCTION AND OPERATION

grade ferronickel or nickel pig iron (NP!) in stainless steel production is a relatively new trend to reduce the cost of high grade ferronickel. In this study, low grade lateritic nickel ores were processed by using carbothermal reduction to produce NP/. The used ore was from Turkey East Anatolian region. In the first experimental set, raw lateritic ore containing 0.9% Ni, 0.054% Co and 2.3% ...

Metalshub - Blog - Nickel metal vs. Ferronickel for the ...

18/07/2019  Ferronickel is a ferroalloy containing mainly iron and nickel. It is supplied in the shape of flowable granules with a typical particle size between 2 and 50 mm. Part of the production process is a refining step which reduces the amount of carbon, silicon, manganese, sulfur, and phosphorus to an acceptable level for foundries.

Production Process of Ferronickel - Miss Rifka

18/12/2018  The choice of saprolite ore ensures that the ferronickel product is not excessively diluted by iron. Production process of ferronickel consists of four main steps. Drying: elimination of most or a substantial portion of free moisture content of the nickel ore; Calcination-reduction: elimination of the remainder of the free ore moisture and its crystalline water, preheating of the ore, and ...

Modelling of Nickel Laterite Smelting to Ferronickel

The activities of iron and nickel in ferronickel alloys were determined by Conard et al. (1978) and showed that the activity coefficient of iron is close to unity and that of nickel is 0.65. The activity coefficients of carbon and silicon in molten ferronickel were estimated using the dilute solution model described by Sigworth and Elliott (1974). A representative activity coefficient of ...
