Magnetic Separation For Nickel Low Noise

The magnetic concentrates were applied to further improve the efficiency of smelting process based on DRMS-RKEF process at laboratory scale, which were produced from nickel laterite A by reduction at 1250 C for 80 min with low-nickel concentrates of 20% (72.43% Fe, 4.65% Ni), composite additives of 5% and C/Fe of 2 followed by subsequent

    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
