Hydrogen peroxide leaching of hydrolyzed titania residue prepared from mechanically activated Panzhihua ilmenite leached by hydrochloric acid

► We introduce a novel method to leach Ti from the hydrolyzed titania residue.► Anatase TiO2 only with impurity of little Si can be easily obtained by this method. ► This method is a simple, efficient, economical, and environment-friendly way for both ilmenite utilization and materials preparation.
