Analysis on Producing High-end Synthetic Rutile from Beach Ilmenite Placer

Analysis on beach ilmenite placer was conducted by X-ray diffraction(XRD) and chemical analysis.Results indicated that the beach ilmenite placer was comprised of 18.1% ilmenite and 77.4% nigrine,and Fe(Ⅱ) in the ilmenite was mostly oxidized to Fe(Ⅲ).The synthetic rutile was prepared from beach ilmenite placer by reduction-fluidization leaching method.Analysis on the synthetic rutile was conducted by XRD,optical microscope,chemical analysis and grain size screening method.The results showed that the synthetic rutile was a rutile type TiO2,in which the content(mass fraction) of TiO2 was 96.12%,the content of CaO and MgO was 0.21% and particle size of +150 μm accounted for 96.5% with perforated hollow structure.It was a high-end product of synthetic rutile and an ideal material for producing chloride titanium dioxide and sponge titanium.
