WebDec 12, 2024 · The production of ferronickel concentrate from low-grade nickel laterite ore containing 1.31% nickel (Ni) was studied by the non-melting reduction magnetic separation process. The sodium chloride was used as additive and coal as a reductant. The effects of roasting temperature, roasting duration, reductant dosage, additive dosage, and grinding … Webat the order of 1.7 wt.% NiO, with amorphous garnierite-type minerals, besides chlorite and likely serpentine, as the Ni-rich phases. An approximately 2 m-long interval defines a transitional zone from the silicatic toward the oxidized ore, marked by the outward gradual absorption of residual blocks from the parent rock within a goethitic plasma. elisabeth cicotti
