Experimental Study on Direct Acid Leaching of Scandium from V-Ti Magnetite Tailings AITranslate
Abstract AITranslate
The content of Sc2O3in the tailings of Bijigou vanadium-titanium magnetite in Yang County,Shaanxi Province is 97.08 g/t.In order to fully recover the rare earth resources,scandium was leached by direct acid leaching,and the effects of acid type and dosage,aid-leaching agent type and dosage,leaching temperature,leaching liquid-solid ratio,leaching time,and feed fineness on the leaching rate of scandium were systematically studied.The results show that without the addition of aid-leaching agent,the leaching effects of H2SO4,HCl,H2SO4+HF,and HCl+HF on scandium in tailings are very poor,but the leaching rate by HCl is higher than that by H2SO4.Adding 2#aid-leaching agent in HCl system can significantly increase the leaching rate of scandium.When the tailings are ground to a fineness of-0.075 mm paticles accounting for 80%,the leaching rate of scandium can reach 89.53%under the optimal conditions of 2#aid-leaching agent dosage of 15%,HCl concentration of 6 mol/L,liquid-solid ratio of 3∶1,leaching temperature of 90℃,and leaching time of 6 h.The direct acid leaching process has a high leaching rate of scandium and is more operatable,which can promote the development of recovering scandium from tailings.
