Study on the Behavior of SiO₂ Related Phases in the Vanadium Slag

Abstract:

The SiO2 related phases in the vanadium slag exist in form of orthosilicate matter, the first solidified vanadium-containing phases would be surrounded or wrapped by the last solidified orthosilicate. So the wrapped orthosilicate have to be broken to achieve the extraction of vanadium from vanadium slag, therefore, to study the characteristics of SiO2 related phases in the vanadium slag will offer a practical guidance to understand the phase change of vanadium slag, The free SiO2 phase isn’t generated in the process of vanadium slag production in this paper by means of combination of vanadium slag compositions, petrographic analysis, Scanning electron microscopy -energy spectrum analysis (SEM-EDS) with the phase diagram of MgO-SiO2-FeO-CaO pseudo-ternary system calculated by Factsage, and SiO2 is mostly present in the olivine and pyroxene minerals.
