Mining of nickel laterites – towards more environment friendly operations

Global demand for nickel (Ni) is expected to increase rapidly by 2030, driven by its use in rechargeable batteries. Over 60% of annual global Ni production originates from Ni-laterites, with Indonesia and the Philippines leading the market. Mining of Ni-laterite ore can adversely affect the environment, through the release of both CO2 and potentially toxic elements, including hexavalent chromium. The crystallographic trapping of both pollutants in carbonate minerals is a novel method that has the potential to alleviate the negative impact of Ni laterite mining, making the growing industry more environment friendly.
