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

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

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 and Zambia. More than six million tonnes of copper-containing materials are smelted each year with ISASMELT technology. Further plants are under construction in Peru and Kazakhstan.

One of the key strengths of the technology is the growing ISASMELT family itself. Xstrata Technology provides on going support to licensees following commissioning of plants and encourages frequent interaction between our own team and those of the clients, as well as interaction between client teams. We hold regular licensee workshops during which technical personnel from smelters all around the world gather to compare operating techniques and discuss how to improve their profitability further. The most recent of these was hosted by Southern Peru Copper Corporation in November 2008. Participants came from Australia, Belgium, Chile, China, Germany, Kazakhstan, USA, Zambia and of course Peru.
