Select An Industry:
Oxygen, hydrogen and hydrogen/nitrogen blends can be used in your acid leaching and refining processes to improve reactions and minimize metallic oxide formation.
Oxygen is a highly reactive gas and promotes the acid leaching process by improving hydrometallurgical reactions between solids and liquids. Oxygen can also be used effectively to oxidize impurities and facilitate their removal. By using oxygen instead of air, the reactions occur more rapidly resulting in less processing time.
