In mining and mineral processing, Air Liquide Australia can provide nitrogen, oxygen and carbon dioxide in large volumes to help you increase efficiency in flotation processes and oxygen enrichment solutions during the roasting process. Air Liquide also proposes reliable and competitive nitrogen on-site generation solutions for the inerting of underground coal mines.

  • Flotation and pH control
  • Roasting oxygen enrichment
  • Nitrogen inerting of longwall underground mines

Air Liquide Australia supports the hydrometallurgy actors by offering solutions for pre-oxidation and leaching processes as well as lithium carbonate purification. By providing oxygen or carbon dioxide, Air Liquide can help greenfield miners to better define their oxygen needs for prospective mines and eliminate the use of chlorine.

  • Gold cyanide leaching
  • Lithium carbonate purification
  • Uranium in-situ leaching


At different steps of the pyrometallurgy processes, Air Liquide Australia provides solutions - gas and technologies - that help customers to enhance purity of metal, increase productivity and maximise the use of their installations.

For example, Air Liquide's oxygen injection technology in smelters and converter reduces energy consumption while reducing environmental emissions of carbon dioxide and nitrogen oxide (NOx).

  • Refining
  • Smelter Oxy-Fuel Enhancement

Air Liquide supplies a range of products, equipment and services for water and wastewater treatment. Carbon dioxide is commonly used for mining effluent pH reduction instead of strong acids. Ozone can recover cyanide from thiocyanate by-product of gold cyanide leaching or destroy residual free cyanide and thiocyanate.

Air Liquide’s innovative and efficient solutions help our customers use water resources responsibly while respecting the environment with regards to wastewater effluent. Air Liquide applies its many years of experience in the water treatment industry to design systems that meet the diverse needs of our customers, all while putting safety and the environment first. We innovate to develop long-term solutions to safely maximise efficiency and robustness while minimising costs and complexity.

  • Cyanide destruction with ozone
  • Cyanide recovery with ozone
  • Acid mine drainage neutralisation
  • Carbon dioxide (CO2) pH control


For over 100 years, welding and cutting gases have been at the heart of Air Liquide’s offer. Over time, our expertise has evolved to meet the changing needs of our customers and technologies.
