摘要
Abstract
Extracting rare earth from waste phosphor using hydrochloric acid was studied .The effects of hydrochloric acid concentration ,the ratio between liquid volume and solid mass ,reaction tempera-ture ,reaction time and stirring speed on extraction of rare earth were investigated .The results show that at the optimum leaching conditions w hich are hydrochloric acid concentration of 2 mol/L ,liquid-solid ratio of 5∶1 ,reaction temperature of 70 ℃ ,reaction time of 4 h and stirring speed of 150 r/min , the leaching rate of rare earth is 83 .45% .关键词
