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 that is simple to operate which can be used for a range of non-ferrous applications, such as copper, lead and tin, 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.

Glencore Technology also produces the ISACONVERT™ continuous converter, based on the ISASMELT™ technology. ISACONVERT™ is an ideal way to upgrade traditional batch converting plants that use Peirce-Smith or Hoboken converters. And unlike the relatively quiescent flash furnace, ISACONVERT’s compact furnace contains a highly agitated molten bath.

You can also learn here about our BBOC - Bottom Blown Oxygen Cupel, a major advance in precious metal refining technology. The technology injects oxygen directly into the reaction zone of the cupel, improving process performance and oxygen utilisation. The technology is well suited to most refining duties where base metals are selectively oxidised and eliminated from precious metal product, such as slimes bullions, PGM-bearing feeds, high purity silver refining and retorted Parkes crust. BBOC™ technology is installed in over a dozen sites worldwide (see our BBOC™ Brochure for more information).
