PROCESS WATER TREATMENT - Acid mine drainage neutralization

In mining and mineral processing, Air Liquide Canada can provide oxygen and carbon dioxide in large volumes to help you increase efficiency in flotation process and prevent high oxygen concentration near the pipe walls (roasting process)

Air Liquide Canada can support the hydrometallurgy actors by offering solutions for preoxidation and leaching process and molybdenite 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.

In different steps of the pyrometallurgy process, Air Liquide Canada provides solutions - gas and technologies - that help customers to enhance purity of metal, increase productivity and maximize 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).
