为满足国防工业发展的要求,云锡公司第一冶炼厂与我所共同进行的盐酸系统连续萃取法提铟试验,已经获得成功,并开始转入生产。该厂铟的生产,过去采用分级中和,酸溶和加硫化钠除重金属提取铟的传统常规流程,存在铟的回收率低,工序繁多,作业周期长,劳动强度大,生产过程产生硫化氢有毒气体和置换产生的硫酸铝废液 In order to meet the requirements of national defense industry development, the Indium Induction Test of Continuous Extraction of Hydrochloric Acid System by the First Smelter of Yunxi Company and our company has been successful and has been transferred to production. Indium production in the past, the use of grading and acid-soluble and sodium sulfide in addition to heavy metals removal of indium traditional conventional processes, there is low indium recovery rate, many processes, long working cycle, labor-intensive, the production process to produce hydrogen sulfide Toxic gases and replacement of aluminum sulfate waste produced
