The flotation process is only suitable for extracting sulphide minerals and has little effect on the recovery..., MA G, DAS A, YOUNG C. Carbothermal reduction of copper smelter slag for recycling into pig iron and glass [J]. Minerals Engineering, 2017, 107: 8-19. DOI: https://doi.org/10.1016/j.mineng.2017.02.006.......
grains is relatively small, and the grains combine with gangue tightly as Na2CO3 is used. While the metallic iron grains grow large and the boundary between iron grains and gangue minerals is clear..., and then providing beneficial way for the gathering of iron grains and gangue minerals. While there is no liquid phase forms in the sodium carbonate redox system, and the migration of iron ions......
Fundamentals of fast reduction of ultrafine iron ore at low temperaturePei Zhao and Peimin Guo State Key Laboratory for Advanced Iron and Steel Processes and Materials, China Iron and Steel Research Institute Group, Beijing 100081, China摘 要:Fundamentals on the fast reduction of ultrafine iron ore at low temperature, including characterization......
and gangue minerals, the main obstacle associated with exploiting these deposits is the poor liberation of iron minerals from gangue minerals [2-4]. Meanwhile, the energy consumption and mineral recovery... are shown in Fig. 1, where some minerals are indicated. Figure 2 shows the X-ray diffraction pattern of magnetite ore sample, indicating that magnetite is the main iron-bearing mineral, whereas quartz......
