Abstract

In this paper the direct reduction melting separation-leaching process is investigated on recovering rare earth from rare earth Bayan Obo complex iron ore (REBOCIO). The REBOCIO was reduced and melting separated to produce iron nugget and rare-earth-rich slag at 1400 °C for 12 or 15 min. The RE2O3 is enriched into Ce4.667(SiO4)O or Ca3Ce2[(Si,P)3O4]3F, which closely depend on chemical components, especially basic. The optimal acid-leaching parameters of rare earth elements from the rare earth slag are suggested as the hydrochloric acid concentration, the ratio of solid to liquid, leaching temperature, and the leaching time are 1 mol/L, 1:14, 50 °C and 120 min, respectively. The rare earth elements leaching efficiency are more than 95%. Adding of calcium CaCO3 and sodium Na2CO3 in direct reduction process have great influence on leaching efficiency of thorium.
