The journey of nickel

It is one of the most widely used processes for extracting minerals like nickel from their ore – the natural rock or sediment that contains them. At the end of the flotation process, the nickel sulphides can be skimmed off and dried. Now at around 18% nickel, the concentrate is driven to Deception Bay, around 100km north of the mine.

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 …
