| 摘 要： | 川西含钪精矿含钪为189.80g/t,主要含钪的载体矿物为绿泥石、蒙脱石、滑石和角闪石,且铁、钙、镁等元素的含量较高,钪的分离难度较大。采用碱熔合—水解—盐酸浸出工艺分离川西含钪精矿中的钪,结果表明:在焙烧温度650℃、焙烧时间15min、碳酸氢钠用量100%、盐酸用量15%、浸出时间75min、浸出温度45℃、液固比为1.5∶1的工艺条件下,获得了钪浸出率99.56%的钪分离指标。浸出渣的化学成分、形貌及能谱分析显示:浸出渣中主要的成分为硅、铝、镁、钪,且钪的含量较低为4.32g/t,浸出渣的扫描电镜分析图谱中没有明显的Sc谱线峰值,这也说明绝大部分钪被溶解进入液相,从理论上验证了钪精矿采用碱熔合焙烧-水解-盐酸浸出工艺分离钪的可行性。
