is known about the molecular mechanism of this process. In this work, a newly developed rutile bio-desilication reactor was applied to enrich rutile from rough rutile concentrate obtained from Nanzhao... in the biological desilication reactor. The results show that TiO2 grade of the rutile concentrate could increase from 78.21% to above 90% and the recovery rate could reach to 96% or more in 8-12 d......

China 25(2015) 2398-2406 Bio-desilication of rutile concentrate and analysis of community structure in bio-desilication reactor Xiang-yu SONG1, 2, Guan-zhou QIU1, Hai-dong... with Sporolactobacillus laevolacticus. The experimental results showed that the TiO2 grade of rutile concentrate increased from 78.21% to 91.80% and the recovery of TiO2 reached 95.24% after 7 d of bioleaching. The bio......
dilute sulfuric acid for 2 h. The XRD patterns show that the product is titanium dioxide with a rutile structure. Mechanism studies show that structures of anosovite solid solution and silicate minerals are destroyed in the roasting process. As a result, titanium components in titanium slag are transformed into TiO2 (rutile) while impurities are transformed into acid-soluble phosphate and quartz. Key......
Fabrication and characteristics of rutile TiO2 nanoparticles induced by laser ablation LIU Pei-sheng(刘培生)1,2,3,4,CAI Wei-ping(蔡伟平)2,WAN Li-xi(万里兮)3, SHI Ming-da(石明达)4, LUO Xiang-dong(罗向东) 1.... The as-prepared products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The results indicate that the rutile TiO2......
