410083, China) Abstract: A novel process was developed to treat the high-aluminum limonite ores. Al-Fe separation from a high-aluminum limonite ore with total iron grade of 48.92% and Al2O3 content of 8.16% (mass fraction) was studied by reduction roasting with addition of sodium salt followed by magnetic-separation. The results show that metallic iron powder with total iron grade of 91.00......

Solvent impregnated resin prepared using task-specific ionic liquids for rare earth separation CHEN Ji1,MA Jiutong2,JI Yang1,SUN Xiaoqi1 (1.State Key Laboratory of Rare Earth Resource Utilization...) was studied for rare earth (RE) separation. Adsorption ability of the SIR was indicated to be obviously higher than that prepared by [A336][NO_3] because of the functional anion of [A336][CA-100]. Adsorption......
