Ferroalloy

Ferroalloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese Mn, aluminium Al, or silicon Si. They are used in the production of steels and alloys. The alloys impart distinctive qualities to steel and cast iron or serve important functions during production and are, therefore, closely associated with the iron and steel industry, the

Production of ferronickel from nickel laterites in a DC

Also, by selective pre reduction of NiO and Fe 2 O 3 in the pre reduction step, the ratio of Ni to Fe in the metal can be controlled to obtain a high grade ferronickel. A lower powered furnace can be used, as the melting requires less energy than is the case for the smelting reactions especially if some SiO 2 were also to be reduced to some significant extent in the smelting process.

Production Process of Ferronickel Miss Rifka

18/12/2018· The generic formula of garnierite, Mg 3 Si 2 O 5 OH 4, is used to represent saprolite ores in chemical reactions. Feed material for ferronickel production is predominantly saprolite, rather than limonite. This is because the iron content of the saprolite ore about 15 Fe, is lower than that of limonite ore. The choice of saprolite ore ensures that the ferronickel product is not
