中文摘要: 以P204和TBP作萃取剂,建立了从冶锌废渣中同时提取镓和铟的新工艺。在大于1 mol/L酸度条件下,用P204-煤油作萃取剂实现了镓和铟萃取分离。经三级萃取后,铟的提取率达到99%以上,镓的萃取率小于1%。在大于4 mol/L酸度条件下,用TBP-煤油作萃取剂可使镓的提取率接近100%,TBP有机相用1.5 mol/L氯化铵溶液反萃,镓的反萃率可达99%以上。该提取工艺操作简单,可实现同时提取工业废渣中的镓和铟。
Abstract:A new process to extract gallium and indium from zinc residues with P204 and TBP as extractant was established. Upon [H ]>1 mol/L, gallium and indium can be separated from zinc residues applying P204 as extractant. Extraction rate of indium and gallium is 99% above and 1% below respectively after 3-stage extraction. With [H ]>4 mol/L, extraction rate of gallium is up to 100% applying TBP as extractant. Stripping rate of gallium from TBP organic phase is 99% above applying NH4Cl as extractant. The developed extraction technology of gallium and indium is simple and meets industrial production requirement.
