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 xide (SO 3) is liberated and reacts with nickel to form nickel sulfate.This mechanism can reduce considerably …
