Study on Leaching of Vanadium From Silicate-type Vanadium Ore

Qian Shi

Abstract

Leaching of Vanadium from silicate-type vanadium ore has been research by roasting and leaching using acid.The optimal conditions were determined that roasting temperature was 800 ℃,roasting time was 3 h,ore granularity was 80% for 0.074 mm diameter granule.Leaching rate of vanadium was up to 85 % at the conditions of leaching temperature of 70℃ and leaching time of 0.5h.
