  • Recovery of nickel and cobalt from leach slurries
    Patent number: 4280988
    Abstract: A slurry, such as might be obtained from acid leaching nickeliferous ores having a high iron content, is treated to separate dissolved nickel or cobalt from iron oxide solids. The treatment involves a controlled precipitation of the non-ferrous metal with the aid of calcium sulfide or barium sulfide followed by flotation to recover a high grade concentrate of the non-ferrous metal.
    Type: Grant
    Filed: April 4, 1980
    Date of Patent: July 28, 1981
    Assignee: The International Nickel Co., Inc.
    Inventors: Kohur N. Subramanian, Gerald V. Glaum, Einar Walli
  • Process for recovering cobalt electrolytically
    Patent number: 4274930
    Abstract: A cobaltic oxide hydrate is mixed with spent sulfate electrolyte and the slurry is sparged with air to liberate any entrained chloride ions as gaseous chlorine. Thereafter a reducing agent is used to enable dissolution of the cobalt and obtaining of a chloride-free solution from which, after purification, cobalt can be electrowon.
    Type: Grant

  • Pelletizing sulfation of anode slimes
    Patent number: 4272493
    Abstract: Anode slimes from an electrorefining operation are fed, together with sulfuric acid, into a heated pelletizer wherein a sulfation reaction occurs, simultaneously with pellet formation, to solubilize copper, nickel and tellurium contained in the slimes.
