CO2 mineral sequestration and nickel recovery from laterite ore by using waste copperas

Yuxiang Gao et al.

Summary: This study proposes a novel process using copperas, a solid waste, to extract magnesium and nickel from laterite ore for simultaneous CO2 mineralization and recovery of nickel. The copperas is decomposed into SO2, sulfating the laterite ore and the addition of Na2SO4 facilitates the formation of low melting point substances, enhancing the extraction efficiency. The heat of sulfation compensates the heat of copperas decomposition, reducing overall energy consumption. The carbonation experiments reveal the optimal CO2 storage capacity of approximately 291 kg.t? 1 laterite ore. Compared to the conventional acid-based Mg extraction process, this cheap method avoids reagent recycling and reduces the amount of alkali used.
