The hydrolyzed titania residue with mainly precipitated hydrated TiO(2) is prepared from mechanically activated Panzhihua ilmenite leached by hydrochloric acid. We use H(2)O(2) as a coordination agent to leach Ti from the hydrolyzed titania residue. The effects of H(2)O(2) to-hydrolyzed titania residue mass ratio, leaching pH value, leaching temperature, leaching time, and H(2)O(2) concentration on leaching of hydrolyzed titania residue by H(2)O(2) are investigated. The recovery of Ti is above 98% under the optimal conditions. XRD shows that the peroxo-titania powder prepared by boiling the aqueous titanium peroxide solution is crystalline anatase phase. A well-crystallized anatase TiO(2) and rutile TiO(2) can be obtained through calcining at the temperature of 800 and 1000 degrees C, respectively. EDS shows that the impurities including silicon are enriched in the leaching slag. Little Si is detected as the only impurity in the synthetic TiO(2) due to the weak alkaline condition of leaching.
