Nickel: A Green Energy Necessity With .

Global nickel deposits come in two types of ore, sulphides and laterites. Sulphides are higher grade and extracted using conventional techniques, while laterites are lower grade and must be extracted through more complex, open-pit mining techniques to remove large volumes of water before refining. Historically, most nickel has come from sulphides for these reasons. But given the increasing ...

After mining, nickel ores are further processed to upgrade their nickel contents from 1-4% typical of the ores to concentrates with grades in the range 10-20%. Concentration involves crushing the ore and separating nickel-bearing from other minerals using various physical and chemical processing methods. The concentrates are then smelted (in a furnace) to produce a sulfide 'matte' with up ...
