X-Ray mapping and the mineralogy pattern of nickel

 · Nickel is predominantly associated with hematite and goethite. Based on the mineralogical analysis of the ore it is observed that remarkable part of nickel is located in hematite. Therefore nickel cannot be released from hematite lattice. The nickel content in the laterite was 0.7 and the cobalt content 0.04 . The chemical

Challenges in processing nickel laterite ores by flotation

 · It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C.Iwasaki et al. (1961) and Nagano et al. (1970) have reported nickel

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
