Latest Patents

Izumi Sugita holds a patent for a hydrometallurgical process for nickel oxide ore. This process utilizes high-pressure acid leaching to achieve a high iron oxidation ratio. The method involves measuring the carbon grade in ore slurry and the flow rate to determine the appropriate amount of carbon to be fed into the system. Subsequently, sulfuric acid is added to facilitate the reaction. The process also includes adjusting the blowing ratio of high-pressure air and high-pressure oxygen to maintain an oxygen purity of 21% to 60%. By controlling the oxygen blowing amount per weight of carbon, the oxidation-reduction potential (ORP) in the leaching treatment is effectively managed.
