Ausmelt® TSL Process - Metso Outotec

Central to the Metso Outotec 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
