Copper-Nickel Ore Processing
Copper Solvent Extraction. The separation of copper from nickel is based on the fact that there is an appreciable difference in the pH at which the two metals are extracted. Copper can be extracted, with very small amounts of nickel, at pH 6.0 to 6.5, while nickel is extracted from the copper raffinate at pH 8.0 to 8.2.

Roasting and Leaching Behavior of Nickel Laterite Ore
The success of the sulfation-roasting-leaching process depends on iron behavior. Due to its higher amount, it is sulfated before nickel. However, the stability of iron sulfates is lower than the nickel sulfate and during the decomposition of iron sulfate, the sulfur trioxide (SO 3) is liberated and reacts with nickel to form nickel sulfate.This …
