in flash smelting, dry sulfide ore containing less than 1% moisture is fed to the furnace along with preheated air, oxygen-enriched air (30–40% oxygen), or pure oxygen. iron and sulfur are oxi-dized. the heat that results from exothermic re-actions is adequate to smelt concentrate, producing a liquid matte (up to 45% nickel) and a fluid slag.
in flash smelting, dry sulfide ore containing less than 1% moisture, is fed to the furnace along with pre-heated air, oxygen-enriched air (30-40% oxygen), or pure oxygen. iron and sulfur are oxidized, and the heat that results from exothermic reactions is adequate to smelt concentrate to produce a liquid matte (up to 45% nickel) and a fluid slag.
