بيت /ferronickel production from oxide nickel ore
In ferronickel production, the nickel oxide and part of the iron oxide are reduced to metal in an electric furnace to form immiscible layers of slag and metal. The crude ferronickel is tapped from the furnace and refined to saleable ferronickel by conventional techniques.

Nickel is mainly used as f erronickel in stainless steel production industry. Its usage as low 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 most common type of nickel ore, in sense of distribution and size of the deposits, is the– oxidesilicate. The oxide form, usually called laterite or limonite overlies the silicate form, garnierite or serpentine, which extends down to contact the unaltered rock. The laterite is characterized by a high iron content, and rela
