In this study, a new process for producing pure titanium oxide from low-grade titanium ore is examined. Titanium ore is reduced to metallic iron and soluble titanium oxide, and then dissolved in an acid solution under hydrogen gas atmosphere to obtain a solution containing titanous ions, ferrous ions, and other soluble impurities.
Jul 10, 2015 However, direct contact between crystalline photoactive titanium dioxide and magnetic iron oxide gives rise to lower photoreactivity than pure titanium dioxide for the pollutant degradation. To overcome the challenge, a number of researches have been done and significant process has been made in this area in recent years.
Geometrical structures of iron oxide cluster cations have been analyzed by ion mobility mass spectrometry. The series of FeOn and FenOn 1 cluster cations were predominantly observed in a mass spectrum at high ion-injection energy into a drift cell. Arrival time distributions in the ion mobility spectrometry indicate that two structural isomers coexist for the FeOn clusters at n 5 ...
Jun 25, 2009 A new type of metal-oxide-coated magnetic nanoparticles NPstantalum-oxide-coated magnetic iron oxide Fe3O4Ta2O5 NPswhich are used as affinity probes for selectively trapping phosphopeptides from complex samples, is demonstrated in this study. In this approach, phosphopeptide enrichment was achieved by incubating the NPs with sample solutions under microwave heating
Apr 20, 2017 Present Practice and State of Development. The largest development in the iron-ore industry, using magnetic concentration, is at the plants of Witherbee, Sherman amp Co. at Mineville, N. Y., where about 1,200,000 tons of crude ore were mined and separated in 1916. The dry process of separation is used.

titanium oxide. Bauxite deposits in different places have different mineralogy IBM 1999. The main problems with bauxite ores are high iron and titanium contents. So, the removal of iron and titanium oxide is required in order to meet refractory specification. Use of gravity and magnetic separations in
Magnetic separation has long been used to upgrade and beneficiate a wide variety of industrial ... The hard rock deposit for Case Study 2 consisted of iron and titanium bearing minerals as well as vanadium and other gangue minerals. The main goal was to recover the abundant magnetite and ilmenite components however,
Issues with existing vanadium beneficiation stimulate the development of new technologies for wasteless production of vanadium. The present work investigates a possibility of beneficiation of vanadium and titanium oxides in a low-titanium magnetite concentrate by using selective reduction and extraction of iron. Iron was selectively reduced by coal without melting and separated from the oxide ...

Iron-titanium oxide mineral contained in Indonesia iron sand are classified as titanomagnetite. Indonesia possesses a lot of iron sand deposits such as at southern coast of Cilacap, Kebumen and other areas. The iron sand consists of magnetic and non-magnetic minerals as either loses or
crude separation of titanium metal. However, it was not until 1910 that M.A. Hunter, an American chemist, produced pure titanium. Ilmenite, the principal titanium ore mineral, was named after the Ilmen Mountains in the south Urals. Titanium, with atomic number 22 and symbol Ti, is one of the transition elements in Group IVB of the per i-odic table.
The invention relates to a method for producing titanium oxide-containing slag and pig iron from ilmenite. The method is characterized in that it comprises the steps a pre-reducing ilmenite in the presence of reductant in a prereduction reactor to metallize at least part of iron in the ilmenite b optionally removing unreacted reductant and gangue from the pre-reduced ilmenite and c ...
