四丁基溴化铵-碘化钾-铟(Ⅲ)三元缔合物浮选分离铟的研究曹书勤1,司学芝1,钟黎1,沈久明1,马万山1(1.河南省信阳市信阳师范学院化学化工学院)摘 要:研究了四丁基溴化铵-碘化钾-铟(Ⅲ)三元缔合物浮选分离铟的行为及与一些金属离子分离的条件.结果表明,在水溶液中,In(Ⅲ)与四丁基溴化铵和KI形成不溶于水的三元缔合物InI4-·TBAB+,此三元缔合物沉淀浮于盐水相上层形成界面清晰的液-固两相.当溶液pH值为2.0,四丁基溴化铵和KI的浓度分别为6.0×10-4 mol/L和5.0×10-3 mol/L时,I......
Trans. Nonferrous Met. Soc. China 25(2015) 1657-1676 Isothermal thermo-analytical study and decomposition kinetics of non-activated and mechanically activated indium tin oxide (ITO) scrap powders... Abstract: Isothermal decomposition process of chemically transforming indium tin oxide (ITO) powders into indium (III) hydroxide powders was investigated. Two types of powders were analyzed, i.e., non......
the heavy and low vapor pressure impurities at low level.As indium has low melting point and high boiling point,it is suitable for refining by vacuum distillation.First,saturation vapor pressure for major elements in crude indium was calculated by the Clausius–Clay Prang equation,which could approximately predict the temperature and pressure during vacuum distillation process.Second,the activity......
Recovering indium with sulfating roasting from copper-smelting ashZHU Guocai,ZHENG Mingdan,FAN Guanglong,and ZHAO Yuna Institute of Nuclear and New Energy Technology,Tsinghua University,Beijing 102201,China摘 要:A technology for recovering indium from Jinchuan copper-smelting ash was developed. Indium in the ash was first enriched to the leaching-slag......
