Experimental study on the flotation of a low-grade graphite vanadium ore

In view of the characteristics of a low-grade graphite vanadium ore in Jiangxi,the process of preferential flotation of graphite and then floating vanadium from the graphite tailings was adopted to recover graphite and vanadium.As a result,a graphite concentrate with carbon grade of 92.06% and recovery of 95.85% and a vanadium concentrate with V2O5 grade of 2.26% and recovery of 77.86% were obtained when the carbon grade and V2O5 grade of the original ore was 6.71% and 0.41% respectively,realizing the comprehensive recovery of graphite and vanadium.
