摘要
论述了铜冶炼过程中产出的含铟砷烟灰,分别用逆流氧化酸浸法和硫酸化焙烧水浸出法提取铟的工艺流程及其技术条件。针对原料的高砷、高铅、高锑以及硅铁含量低的特点,采取行之有效的技术措施,产出质量为99 99%铟。
The paper describes the process and technology for Indium recovery from Arsenic flue dust of Copper smelter, and two processes of counter current sulphation-oxidizing leaching and sulphation roasting-water leaching respectively. Counter to the raw material contains high Arsenic、high Lead、high Antimony and low Silicon、low Ferrooxidans, good measures were adapted Indium more than 99.99% is produced.
