The Prospect of Recovering Vanadium, Nickel, and Molybdenum from Stone Coal by Using Combined Beneficiation and Metallurgy Technology Based on Mineralogy Features

Black shale ore contains rich strategic metal resources such as vanadium, nickel, and molybdenum, but due to its complex composition, it is currently only used in the vanadium extraction industry. Metals nickel molybdenum have not been effectively recovered, resulting environmental pollution resource waste. Using mineralogical features a combination of beneficiation metallurgy-based tests, present work carried out feasibility studies combined metallurgy processes. The stone coal sample were studied using chemical analysis, an automatic mineral analyzer (BPMA), etc., we identified main phase embedded characteristics, particle size distribution associated metals, molybdenum. results showed that grade V2O5 was 1.29%, which mainly carbonaceous clay mica minerals. 0.53%, form nickel–magnesium spinel small amount nickel-containing magnesite. contained 0.11% molybdenum; particles fine, mostly molybdenite, some with matter Based on feature, proposed scrubbing–desliming flotation process enrich Our preliminary experiments obtained two products: vanadium–molybdenum-rich sludge tailings. grades 4.10% 0.44%, respectively, recovery 41.31% 51.40%, respectively. tailings 1.49%. These products roasted leached. recovered through beneficiation–metallurgy process, comprehensive utilization rate improved.
