Production of Nickel Oxide From Ammoniacal Process Streams

At its iron ore recovery plant at Copper Cliff, !NCO produces about 17 million pounds per year of a pure, acidsoluble, dense nickel oxide from nickeliferous pyrrhotite. The process used is also applicable to a broad range of ammoniacal nickel-bearing streams. The product has been widely accepted by the chemical, ceramic and electronic industries.
