    Frontiers A Robust Recovery of Ni From Laterite Ore

    Laterite ore is one of the important sources of nickel Ni. However it is difficult to liberate Ni from ore structure during reduction roasting. This paper provided an effective way for a robust recovery of Ni from laterite ore by H2 reduction using sodium thiosulfate Na2S2O3 as a promoter. . It was found that a Ni content of 9.97 and a Ni recovery of 99.24 were achieved with 20 wt .
