Effectiveness of sodium silicate as gangue depressants in iron ore slimes flotation

引用

International Journal of Minerals,Metallurgy and Materials 2011年第5期18卷 515-522页

作者： Danda Srinivas Rao Tadiparthi Venkata Vijayakumar Sripada Subba Rao Swarna Prabhakar Guntamadugu Bhaskar raju National Metallurgical Laboratory-Madras Centre Council of Scientific and Industrial Research-Madras ComplexChennai 600 113India

The recovery of iron from the screw classifier overflow slimes by direct flotation was studied. The relative effectiveness of sodium silicates with different silica-to-soda mole ratios as depressants for silica and silicate bearing minerals was investigated. Silica-to-soda mole ratio and silicate dosage were found to have significant effect on the separation efficiency. The results show that an increase of Fe content in the concentrate is observed with concomitant reduction in SiO2 and A1203 levels when a particular type of sodium silicate at a proper dosage is used. The concentrate of 58.89wt% Fe, 4.68wt% SiO2, and 5.28wt% A1203 with the weight recovery of 38.74% and the metal recovery of 41.13% can be obtained from the iron ore slimes with 54.44wt% Fe, 6.72wt% SiO2, and 6.80wt% A1203, when NazSiO3 with a silica-to-soda mole ratio of 2.19 is used as a depressant at a feed rate of 0.2 kg/t.

Optical parameters induced by phase transformation in RF magnetron sputtered TiO2 nanostructured thin films

引用

Progress in Natural Science:Materials International 2014年第3期24卷 218-225页

作者： Prabitha B.Nair V.B.Justinvictor Georgi P.Daniel k.Joy k.C.James raju David Devraj kumar P.V.Thomas Thin Film Lab Post Graduate and Research Department of Physics Mar Ivanios College 2. School of Physics University of Hyderabad Central University P. O. 3. College of Education Florida Atlantic University

Pure TiO2 thin films were deposited onto quartz substrates using a ceramic TiO2 target at an elevated substrate temperature of 573 k by RF magnetron sputtering, and an analysis of structural, optical and photoluminescence characteristics of the films upon phase transformation is reported in this paper. Structural investigations using X-ray diffraction revealed that the as-deposited film was amorphous in nature. Thermal annealing for 2 h at 873 k in air resulted in the formation of anatase phase, and a phase transformation to rutile was observed at 1073 *** increase in grain size and an improvement in crystallinity were also observed on annealing. Rod- like rutile crystallites were observed in the SEM images of the film annealed at 1273 k. As-deposited films and films annealed up to 1073 k were highly transparent in the visible region with a transparency 480%. Optical band gap of the films decreased upon thermal annealing which is attributed to phase transformation from amorphous to anatase and then to rutile. Optical parameters such as refractive index, optical conductivity and optical dielectric constant increased with increase in annealing temperature. Since rutile is the optically active phase, the superior refractive index of the film annealed at 1073 k along with its high transparency in visible region suggests the application of this film in antireflective coatings. Photoluminescence emission of maximum intensity was observed for the film annealed at 873 k, which exhibits anatase phase. Intense blue emission observed in this film makes it suitable for use in optoelectronic display devices.
