-Ti magnetite tailings using roasting and leaching[J]. The Chinese Journal of Nonferrous Metals, 2021, 31(6): 1611-1620. DOI: 10.11817/j.ysxb.1004.0609.2021-36561 钪属于广义的稀土元素,也是典型的稀散元 素[1].全世界钪储量约为200万... leaching 2.1.2 氯化镁用量对钪浸出的影响 由于精矿矿中含有Ca2+,Al3+,Na+等可被氯化的金属离子,若是氯化剂用量过少,那么ScCl3的产量也会相应减少,导致浸出率过低；但用量过大,又会造成药剂浪费,增加成本,因此,有必要分析氯化剂用量对钪浸出过程的影响. 进行相关试验分析氯化镁用量对钪浸出的影响,具体试验流程为:将MgCl2与钪粗精矿混合均匀加水制粒烘干后,在900......
