Harnessing the capability of fungi to dissolve large quantities of nickel and cobalt from laterite ores will create a step change in the technology for processing nickel laterites and other oxide minerals. Using microorganisms and their metabolic products promises to be effective, energy saving, easily controlled and environmentally safe. The mechanistic investigation proposed in this study will generate fundamental innovations and technological advancement in bio-leaching of laterite ores. Such technologies can secure the sustainability of nickel production and provide unique ecological reform to the mineral extraction industry.
