摘要
Abstract
The mineral composition and valence state composition of vanadium clinker in vanadium slag and salt-free roasting stage at different temperature nodes were studied by photoelectron spectroscopy and mineral analyzer.The results show that the contents of vanadium spinel,ferroolivine and calciferite decrease with the increase of roasting temperature,while the contents of iron oxide,ferrotitanite and manganese vanadate increase with the increase of roasting temperature.With the increase of roasting temperature,the oxidation of vanadium slag from V3+to V4+is gradually transformed into the internal oxidation of V3+to V4+and V4+to V5+.The valence state of vanadium in vanadium spinel is V3+and the valence state of vanadium in oxidation state is V4+.The mineral analysis results of vanadium slag and clinker are in good agreement with the valence analysis results of vanadium element.关键词
