Clean, cost-effective smelting with a high intensity submerged lance

Glencore Technology’s ISASMELT™ provides an innovative, high intensity, yet low cost submerged lance smelting process. It is simple to operate which can be used for a range of applications including copper and lead smelting as well as recycling.

The process is fully enclosed, and operates in regions with some of the toughest emission standards. The proven technology has been in operation for over 30 years, and achieves design targets quickly - ramp up times of 3 months are not uncommon - and are achieved with the training and support that Glencore Technology provides.

ISASMELT™ is installed in major lead and copper smelting and converting operations around the world, including Australia, USA, Belgium, Germany, Great Britain, India, Malaysia, China, Kazakhstan and Zambia. More than nine million tonnes of copper-containing materials are smelted each year with ISASMELT™ technology.
