摘　　要：根据某多金属矿石的矿物组成及前期试验成果,研究了采用焙烧—水浸工艺回收铷,考察了添加剂用量、焙烧温度、焙烧时间和矿石粒度等因素对铷浸出率的影响,确定了最佳焙烧—水浸工艺条件。试验结果表明,最佳条件下,铷浸出率达到95%以上。Based on the ore composition and previous research results in lab ,the salt roasting‐water leaching of the ore for extracting rubidium was investigated .The effects of additive amount ,mass proportion of calcium chloride to sodium chloride ,roasting temperature ,roasting time and particle size of ore on the leaching rate of rubidium were examined .The experiments result show that the leaching rate of rubidium is more than 95% under the optimum conditions .
