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 (organics)

Carrying nickel ore: The world’s most dangerous cargo ...

07/04/2017  The intention of the Indonesian export ban was to stimulate the country’s mining industry to build smelter facilities to process the ore locally prior to export. Prior to the ban, Indonesia and the Philippines accounted for over 60% of the worlds nickel ore exports, with the ore mostly destined for ports in China. By 2014, mines in the Philippines accounted for 50% of the worlds exports of nickel ore filling the Indonesian export void and remain the top nickel ore

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: 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 ...
