研究了氯化钠—丙醇体系溶剂浮选铋的行为及丙醇水溶液的分相条件。实验表明 ,当溶液pH =5～ 7时 ,Bi 水解生成碱式盐〔Bi(OH) 2 Cl〕沉淀可以溶剂浮选于丙醇与水两相界面之间。此时 ,Bi 可与Cd ,Mn ,Mo ,Fe ,Ni ,Zn 等得到满意的分离
The behavior of solvent flotation of bismuth in sodium chloride-propanol system and the separation conditions of propanol aqueous solution were studied. Experiments show that when pH = 5 ~ 7, Bi is hydrolyzed to form basic salt [Bi (OH) 2 Cl]. The precipitate can be solvent-flotated between the two phases of propanol and water. In this case, Bi can be satisfactorily separated from Cd, Mn, Mo, Fe, Ni, Zn and the like
