用氯化胆碱-草酸从次氧化锌粉尘中梯级分离铟及伴生元素
Step-up Separation of Indium and Associated Elements from Zinc Oxide Dust Using Choline-Oxalic Acid Chloride
摘要
Abstract
In order to efficiently enrich indium(In)in zinc oxide dust and realize the directional separation and recovery of associated elements,Zn,Fe,Pb and In were leached from the dust by choline chloride-oxalate dihydrate low eutectic solvent,and the"hydrolytic removal of zinc and lead-ultraviolet light reduction iron removal"process was used to remove impurities step by step.The results show that the leaching rates of Zn,In,Pb and Fe can reach 95.52％,88 91％,80.82％and 89.13％,respectively,under the optimal leaching conditions of liquid volume to solid mass ratio of 12 mL/1 g,temperature of 70 ℃ and time of 6 h.Zn/Pb is removed by hydrolytic precipitation,and then Fe is removed by ultraviolet reduction precipitation.After the step-by-step precipitation and impurity removal treatment,the mass fraction of indium in the solution has increased from 0.03％to 1.5％,successfully achieving efficient enrichment of indium and directional separation and recovery of associated elements such as Zn,Pb,and Fe.关键词
