the storage and recycle of plant process water. However, there may be a need to treat bleed streams of some process effluents to prevent a buildup of various impurities. Solid wastes from nickel sulfide ores often contain other metals such as copper and precious metals, and con-sideration should be given to further process-ing for their recovery.

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.

Two broad ore types. Nickel occurs in two broad ore types: laterite (oxide) ores, principally located in tropical and sub-tropical areas, and; sulfide ores, principally located in the temperate to sub-Arctic regions. Major nickel mining locations are depicted in the map – but some of these locations have many operations, and some only one.
