    Jan 22, 2016 Since the separation of iron grains and P-bearing slag was not achieved at the low temperature under the conventional conditions, separate experiments of the iron phase and the P-bearing slag phase from gaseous-reduced, high-phosphorous oolitic iron ore at 1473 K 1200 C by super gravity were carried out in this study..This work presents a semi-smelting reduction and magnetic separation process for the recovery of iron and alumina slag from iron rich bauxite ore. The effect of the process parameters on the recovery rate of iron, maximum particle size of the iron nugget, and the Al2O3 content of the alumina slag was investigated and optimized. The results show that the iron nuggets and alumina slag can be ....A study of silica and iron recovery from the iron ore concentration tailing is presented. The residue is composed of 40.1 Fe, 33.4 SiO2, 8.31 Al2O3, 0.08 P, and 0.34 MnO. The developed process of silica and iron recovery consisted of size classification, magnetic separation, and removal of impurities by leaching. A concentration of SiO2 from 33.4 to 67.0, with 60.0 of mass reduction ...
