Nature of the Losses of Nickel with Iron-Silicate Slags During the Production of Ferronickel from Oxidized Ores.

Electrochemical losses of nickel with slag are determined to a considerable extent by the oxygen partial pressure in the gaseous phase. At low values of the oxygen potential of the gaseous phase mechanical losses play a dominant role in the overall losses of nickel with waste slags. The presence of a solid charge containing carbon over the slag melt during the smelting of ferronickel should reduce the electrochemical losses of nickel with waste slags.
