May 19, 2017 · Metal drops form at 1300°C in the presence of either cock or anthracite, their number and size being greater with the former reductant. Figure 4 b shows the phases present at 1550°C when the reductant is coke. It can be seen that coke is a more effective reductant at 1550°C than anthracite.

Additives in Selective Reduction of Lateritic Nickel Ores ...

Jul 07, 2021 · In this work, the selective reduction of lateritic nickel ore was carried out using sodium sulfate, sodium carbonate, and sodium chloride as additives. The 5 wt% of anthracite coal, which contains 60.35% of fixed carbon and 1.9% of sulfur, was used as a reductant. All raw materials were mixed homogenously prior to the pelletization process into 10–15 mm of diameter. The reduction
