Experimental Studies On Enriching Vanadium From Vanadium Tailings Carbon - Containing Pellets By EAF Melting

摘要

The process of smelting reduction by electric arc furnace was adopted to enriching vanadium to iron from vandium tailings, study the effect of vanadium recovery in the carbon-bearing pellet with different coal ratio, alkalinity and smelting time. Design experimental scheme using orthogonal test principle and experimental results was systematically analysed by the comprehensive methods of intuitive analysis and the optimum process parameters were determined. The optimized process conditions are obtained by one-factor at a time tests for recovery vanadium from vanadium tailings as follows: coal ratio of 12%, alkalinity of 1.5, roasting time of 15min.
