A new bauxite-type vanadium ore with a grade of 0.96% V2O5 was found in Hanzhong, China, having quartz, illite, and calcite as the main mineral constituents and vanadium that mainly occurs in the aluminosilicate lattice of illite by replacing Al3+ with V3+ in isomorphism form. In this study, a novel...
