Abstract:
According to the low grade and economic value of vanadium titano-magnetite melting and separation TiO2 slag, the TiO2 enrichment process was studied with hydrochloric acid as the leaching agent, and the influences of leaching time, leaching temperature, concentration of hydrochloric acid as well as acid slag ratio to Ti, Ca, Mg, Al were focused in this paper. The results showed that the optimal acid leaching parameters of TiO2-rich slag were suggested as follows: the leaching time as well as temperature, the concentration of hydrochloric acid, and the ratio of solid to liquid were 3h, 70℃, 4.5mol/L and 0.5, respectively. The content of TiO2 in TiO2-rich slag could reach 70.74% and the loss rate in the solution was only 2.14% which achieved the purpose of the leaching process.
