From sulfide ores. Sulfide ores are crushed and ground in order to liberate nickel minerals from the waste materials by selective flotation. In this process, the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubbles. As these rise through the mixture, the sulfide particles adhere to their

prices and decrease in the reserves of sulphide ores. Laterite nickel ores typically occur in tropical or sub-tropical regions consisting of weathering of ultramafic rocks which contain iron and magnesium in high levels. These deposits usually exhibit different layers due to weathering conditions such as a silica rich layer, a limonite layer [dominated by goethite [FeO(OH)] and hematite (Fe203

Processing of Nickel Laterite Ores on the Rise

Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the nickel industry.

Nickel Sulfide Versus Laterite : The Hard Sustainability

The principal reason for this historically is that sulfide ores are easier to process, through conventional mining, smelting and refining, compared to laterite ores which require intensive hydrometallurgical processing (such as high pressure acid leaching or HPAL). This means that laterite ores typically require substantially more energy and chemicals to produce than sulfide nickel. Given that

The nickel content of laterites varies widely: at Le Nickel in New Caledonia, for example, the ore delivered to the smelter in 1900 contained 9 percent nickel; currently it contains 1 to 3 percent.
