How it works

ISASMELT™ is a simple, highly efficient bath-smelting process for the production of non-ferrous metals. It is recognised as the most innovative, efficient and cost effective smelting process available in the world and since going into commercial production in the 1990s it has been installed in major brownfield and greenfield plants around the world.

The ISASMELT™ process was jointly developed by Mount Isa Mines, a subsidiary of Glencore, and the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO). 

ISASMELT™ utilises a cylindrical refractory lined furnace and operates with a single submerged combustion lance to create a highly turbulent bath.
