Mr Justen Bremmell pours molten slag and alloy from CSIRO's bath smelting facility. Red hot molten slag material pours down a ramp out of the furnace and sparks fly. Mr Bremmell is protected by a full face visor and hard hat, and leather jacket gloves and apron.

High temperature processing

High temperature processing is used to produce metals and advanced materials, and is also used to treat industrial by-products.

The use of high temperatures to extract minerals from ores has long been the backbone of metal production.

High temperature processes are used to produce a range of metals including:

  • steel
  • aluminium, titanium
  • copper, nickel, zinc, lead
  • platinum, tantalum, tin.

High temperature processes are also used in advanced materials processing and in the treatment of industrial by-products.

Our research teams are able to develop new and optimise existing high temperature metallurgical processes.

Modern smelting tends to be highly intensive and requires flexibility; stringent dynamic control is essential.

Our research teams are able to develop new and optimise existing high temperature metallurgical processes.

The team offers a range of expertise including:

  • smelting and roasting chemistry
  • electrochemistry of molten salts and ionic liquids
  • processing biomass for metallurgical applications.

High temperature processing is proving a key technology in advancing today's drive for sustainable processing within the minerals industry. 

Our expertise is being applied in a number of projects that aim to:

  • reduce energy use and greenhouse gas emissions in mineral processing
  • reduce water use in mineral processing
  • manage minor toxic elements
  • recover values through by-product processing.
