摘要
Abstract
Recovery of rare earth from waste polishing powder was researched .The influence of pretreatment ways ,roasted product size ,NaOH amount ,roasting temperature and roasting time on leaching of rare earth using hydrochloric acid were examined .The optimum conditions are determined as mass ratio of NaO H-to-w aste of 0 .18 ,roasting temperature of 450 ℃ ,roasting time of 2 .5 h , roasting product size of 150 mesh .Under the optimal conditions ,leaching of rare earths is over 98% .关键词
