Oxygen in pre oxidation / Leaching - for GOLD

Air Liquide has capabilities to determine the oxygen demand of gold ore/concentrate, helping greenfield miners to better define their oxygen needs for prospective mines. Our team can help optimise oxygen transfer to the pulp by measuring the mass transfer coefficient of dispersion devices and evaluate /optimise leaching reagent consumption. Through properly managed oxygen addition we can help you to improve gold recovery, increase throughput and/or reduce cyanide consumption. We can also assist our customers to measure dissolved oxygen in leach tanks or autoclaves with our patented wireless DO monitoring technology.
