Nickel: A Green Energy Necessity With Environmental

29/07/2018  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 ...

Mining and concentrating where you utilise the run of mine ore and put it through a flotation circuit, in turn upgrading the ore from a low-grade concentrate (say 3 % Ni) to a much higher grade (up to 25% in some cases). This allows the miner to reject the majority of the material mined before complex processing takes place, reducing costs. In addition, chemicals used are not typically harsh ...
