【Abstract】 According to the composition of the rare earth ores and the market, several feasible separation processes of ion adsorptive deposit in Ganzhou(Jiangxi Province) by solvent extraction in HEH(EHP) HCl system combined with naphthenic acid HCl system were presented. The parameters of the processes such as stage numbers, volume of mixer settler, fixed investment of extractant and rare earths, consumption of chemical reagents including HCl and NH 3, were calculated and compared. The results show that the novel scheme can save 5%～50% costs than others. By the economical analysis, the optimized separation process of ion adsorptive deposit was obtained.更多还原
