Iron-doped TiO2 nanopowders with different doping amounts have been prepared by co-precipitation method followed by heat treatment. The obtained materials were structurally, morphologically and analytically characterized by X-ray diffraction (XRD), FT-Raman spectroscopy, diffuse reflectance spectroscopy (DRS) and energy dispersive X-ray …
The physical separation method has low production costs and simple process, but the recovery efficiency of iron from RM is quite low due to the weak-magnetism of hematite and the impurities in the concentrate such as Al 2 O 3 and TiO 2 are still high due to the complex mineralogical paragenetic relationship, thus the iron …
Filtration is a separation method used to separate out pure substances in mixtures comprised of particles—some of which are large enough in size to be captured with a porous material. Particle size can vary considerably, given the type of mixture.
TiO 2 based materials have attracted significant interest in many fields of applications owing to their unique characteristic features. TiO 2 is well known for its photocatalytic activity including water splitting and degradation of organic molecules in particular. H 2 is considered to be a future clean fuel due to the depletion of fossil fuels. …
Iron sand collected with traditional gravity separation method contained 8 to 12% TiO2, while iron sand collected with modern magnetic separation method contained less than 5% TiO2. When gravity-separated iron sand was used in a tatara under strong reducing conditions, zuku (cast iron) flowed out of the tatara.
