  • Patent number: 9617619
    Abstract: Provided is a hydrometallurgical process for nickel oxide ore by high pressure acid leach that achieves a high iron oxidation ratio. The carbon grade in ore slurry and the flow rate are measured to determine the amount of carbon to be fed, and then, sulfuric acid is added. The blowing ratio of high pressure air and high pressure oxygen is adjusted so as to attain an oxygen purity of 21% to 60%. While the oxygen purity is maintained, an oxygen blowing amount per weight of carbon contained in the ore slurry and fed in the second step is adjusted to 200 to 600 Nm3, whereby ORP (Ag/AgCl basis) in the leaching treatment is controlled to 400 to 650 mV.

  • Patent number: 9512503
    Abstract: A hydrometallurgical method for nickel oxide ores, whereby the pH of a neutralized solution can be stabilized. The hydrometallurgical method comprises a sulfuric acid leaching step of leaching an ore slurry of a nickel oxide ore with sulfuric acid, a neutralization step of neutralizing a crude nickel sulfate aqueous solution by adding a neutralizing agent thereto, and a dezincification step of removing zinc as zinc sulfide by adding a sulfurizing agent to a neutralized solution; wherein in the neutralization step, the amount of the neutralizing agent added is adjusted using, as an index, a neutralizing agent addition ratio that indicates the amount of the neutralizing agent added relative to the amount of free sulfuric acid in the crude nickel sulfate aqueous solution.

  • Patent number: 6544663
    Abstract: An object of the present invention is to provide a copper foil having excellent adhesion to an etching resist layer, without performing physical polishing such as buffing in pre-treatment of an etching process to form a circuit from the copper foil. To attain the object, in electroforming, a titanium material having a grain size number of 6.0 or more is employed as a copper deposition surface of the rotating drum cathode, and glue and/or gelatin is added in an amount of 0.2-20 mg/l to a copper sulfate solution, thereby producing a drum foil. An electrodeposited copper foil obtained from the drum foil, wherein 20% or more of the crystals present in a shiny side surface of the electrodeposited copper foil have a twin-crystal structure, is used for producing copper-clad laminates.
