Ausmelt TSL Process in brief

Based on Top Submerged Lance (TSL) technology, the Ausmelt TSL Process has become a leading smelting technology due to its versatility, cost effectiveness and environmental benefits. It is equally suitable for new installations and for modernization of existing smelting plants.

The Ausmelt TSL Process is based on injecting air, oxygen and fuel directly into the molten slag bath via a vertically suspended lance. Critical process phenomena, such as feed material dissolution, energy transfer, reaction and primary combustion, take place in the intensely agitated slag layer. As a result, the Ausmelt TSL Process is extremely efficient with high specific smelting rates. Metso Outotec’s commitment to the continuous development of the Ausmelt TSL Process - in close collaboration with our customers - ensures you receive a best practice solution.
