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
