HYDROMETALLURGY

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.

PROCESS WATER TREATMENT

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 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.
