Project @ a Glance     

  • Commercial basic nickel carbonate is made by precipitation from a nickel solution, usually the sulphate, with sodium carbonate
  • Nickel carbonate can be prepared by the oxidation of nickel powder in ammonia and dioxide. Boiling away the ammonia causes precipitation of pure nickel carbonate
  • There are differences in the manufacturing conditions and precipitation agents used for the production of pure nickel carbonate and nickel hydroxycarbonates
  • Nickel carbonate is produced at lower temperatures (< 50 C) and at lower pH (< 5) than production of basic nickel carbonates. Alkaline bicarbonates are also used instead of carbonates
  • Nickel hydroxycarbonate is mainly produced from either nickel sulphate or nickel nitrate
  • The major uses of nickel carbonate described above result in the production of catalysts, plated products and other nickel-containing chemicals. In these processes nickel carbonate is converted into other nickel-containing compounds. Nickel catalysts and many plated products are recycled
