Central to the Metso 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. This results in a high production capacity from a relatively small diameter furnace, keeping the plant footprint small and making the process ideal for sites with limited space.
