A Robust Recovery of Ni From Laterite Ore Promoted by …
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% …

Laterite Ore
A typical laterite ore may contain approximately 1–1.5% Ni with 40–50% Fe existing in the form of goethite [ (FeNi)O⋅ (OH)⋅ n H 2 O]. Laterite ores contain up to 40% of free and combined moisture, which is removed in the reduction process ( Ray et al., 2014 ). Similar to copper extraction, nickel ores are first beneficiated to produce ...
