Beschreibung
Zusammenfassung:	The invention discloses a classified ore dressing method of calcareous and siliceous mixed type stone coal vanadium ore. Main minerals of raw ore consist of 20-28wt% of quartz mineral, 10-15wt% of mica mineral, 5-10wt% of tourmaline-amphibole mineral and 35-40wt% of carbonate mineral; the grade of vanadium in the raw ore is 0.6-1wt%. The classified ore dressing method comprises the following steps: a) grinding crushed raw ore in a ball mill, and classifying ore materials according to classification size of 0.037-0.075mm to obtain coarse and fine products; b) regrinding the coarse products, then recovering vanadium by adopting a forward flotation process, and removing carbonate in the fine products by adopting a reverse flotation process to obtain vanadium concentrate and calcium concentrate. The method can be used for treating calcareous and siliceous mixed vein type stone coal vanadium ore with the vanadium grade of 0.6-1wt%, the concentration ratio of the obtained vanadium concentrate V2O5 reaches more than 2.5 and the vanadium recovery rate can reach more than 85 percent.
