“…Moreover, a lot of metal particles with size of 9-25 µm were formed in sample C1.4-F12 (Figure 4g), which was rare in sample C1.4, indicating that the addition of CaF 2 promoted the formation of molten slag, thus accelerated the agglomeration of metal particles. In addition, the EDS elemental mappings of sample C1.4-F12 shown in Figure 4i revealed the coexistence of Fe and Ni elements in the formed particles after the carbothermal reduction process, further demonstrating the formation of ferronickel particles, which is consistent with the previous works [14,17,25]. The presence of Mg, Si, and O elements within the same area suggested the formation of magnesium silicate.…”

“…For the bottom saprolitic nickel laterite ore, it is difficult to concentrate nickel and iron through physical beneficiation due to its low nickel and iron content and the highly distributed garnierite [12]. With the export restriction and depletion of high-grade nickel laterite resources, the exploration and utilization of low-grade nickel laterite ore treatment possess broad development prospects owing to its rich reserves, low exploration cost, and mature smelting technology [13][14][15].…”

“…The Fe, Cr and Ni grades in the Fe-Cr-Ni-C alloy are 62.7%, 18.9% and 4.1% respectively. The alloy has low levels of the harmful elements S and P. 27) Chen et al prepared carbonaceous pellets with zinc-containing dust and chromiumcontaining sludge as the main ingredients. Thermodynamic analysis and XRD were used to characterize the mechanism of carbothermal reduction.…”
