Research on Analysis of Tailing Mineral Materials Based on Chemical Analysis and Spectral Measurement

Abstract

Tailings are the election of the remaining ore concentrate in solid waste in particular economic and technical conditions, which contains a number of useful mineral materials. This research collected some samples from vanadium-titanium magnetite tailings, and operated spectral measurements and chemical analysis in the laboratory. Research can improve material analysis methods and mechanisms. Firstly, X-ray diffraction analysis, silicates analysis and spectroscopy detection. It is found that the main mineral composition is plagioclase, chlorite, calcite and quartz. Their content is relatively stable, the material component is insignificant. The main chemical composition was SiO2 and Fe2O3, about 20% or more, 30% of single-element O, 20% of Si, Fe 18% and so on. Secondly, spectrometer measurement. There is little change in spectral reflectance. Spectral characteristics of reflectance curve of analog spectral on TM band were entirely consistent with their of spectral reflectance curves of Samples measured, but measured spectral reflectance curves showed more obvious reflection peak and absorption peak. Therefore, analyzing mineral composition and tailing materials, using remote sensing technology, physical and chemical test method, can explore the inner links and coupling relationship of tailings.
