Ausmelt/Isasmelt feed is moist concentrate, flux and recycle materials, sometimes pelletized. Drying of the feed is not necessary because the smelting reactions take place in the matte/slag bath rather than above it. Moist feed also decreases dust evolution. Oxygen enrichment of the air blown into an Ausmelt/Isasmelt furnace is standard ...

Operation. Central to the Ausmelt® TSL process is the use of a vertically suspended lance submerged in the slag layer of the molten bath. Injection of fuel and process gases (air and oxygen) result in significant bath agitation and mixing, delivering a high-intensity, dynamic smelting process with highly specific smelting rates.
