Study on Extracting Vanadium from Coal Vanadium Ore

Abstract:

Coal vanadium ore from Hunan was pretreated by sulfuric acid for curing. Influences of curing time, curing temperature, sulphuric acid concentration and ore size fraction on vanadium leaching rate were investigated and discussed. Test results showed that: -100 mesh ore size was cured by 20% added quantity of sulphuric acid at 180°C for 24h and was leached by agitation with tap water, the liquid solid ratio of 4: 1 at room temperature for 12h, vanadium leaching rate was 74%
