Flotation recovery of vanadium from low-grade stone coal
W Li, SUN Wei, R Liu, X Gu - Transactions of nonferrous metals society of …, 2014 - Elsevier
Pre-concentration of vanadium from low-grade stone coal by the method of desliming–
flotation was investigated. The mineral composition and microstructure of stone coal were
studied systematically by means of X-ray fluorescence spectrometry (XRF), X-ray diffraction
(XRD) and scanning electron microscopy (SEM). The results show that selective separation
of vanadium-bearing minerals can be achieved by flotation in acidic solution using
melamine (EA). The final vanadium concentrate with V 2 O 5 grade of 1.88% and recovery …
