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.
