Leaching of primary copper sulfide (chalcopyrite) using ferric as the oxidant at ambient temperature and pressure exhibits slow kinetics and poor leaching efficiency. In collaboration with LeadFX, this project aims at developing an atmospheric tank leaching process for copper extraction from chalcopyrite concentrate with iodine as the catalyst. The temperature used will be higher than […]

Both global warming and increasing supply of nickel and cobalt are urgently world-wide issues to be addressed. Mineral carbonation is a promising method to permanently store greenhouse gas CO2 into stable mineral carbonates but energy-intensive requirements and low-value products limit the successful application. Meanwhile, with the increasing demand on global nickel and cobalt supply for […]
