  • Minerals Free Full-Text Preparation of High Purity

    Stone coal is a kind of carbonaceous shale which looks like coal but mostly consists of quartz and with a low calorific value . Typically, vanadium in stone coal exists in the isomorphism-like form in which vanadium replaces trivalent aluminum in the mica structure . The mica structure is stable, so the key step of extracting vanadium from

  • Pre-concentration of vanadium from stone coal by gravity

    Jun 10, 2013· A new process for pre-concentration of vanadium from stone coal by gravity separation was investigated based on mineralogical study. It was confirmed that the vanadium occurred in muscovite and illite, and the acid consuming minerals were pyrite and calcite.
