Abstract

Abstract

Selecting the chlorine slagging after concentration as a raw material,the influence of the leaching sour type,raw material granularity,the leaching acid concentration,the leaching liquid solid mass ratio,the leaching temperature and the extraction time on the scandium leaching rate have been studied.The condition experiment and orthogonal test indicate that the superior experiment condition is:the leaching sour is the sulfuric acid;the leaching acid concentration is 40%;the granularity of the raw material is 44μm(325 items);the leaching liquid solid mass ratio is 3.5;the leaching temperature is 70℃;the extraction time is 8 h.The leaching temperature,leaching liquid solid mass ratio and leaching acid concentration to the leaching rate influence size in turn are:The leaching temperature is more than the leaching liquid solid mass ratio,and the later is more than the leaching acid concentration.The stability test indicated:The scandium leaching rate may reach above 95%,and it creates the advantage to carry on the scandium recycling.
