摘要
本文报导了用酸性五氯化锑溶液作浸出剂浸出硫化锑矿生产锑白的新工艺。本工艺包括浸出、还原、水解、中和、浸出剂再生等主要过程,产品质量符合我国三氧化二锑标准中的零级标准,浸出剂经氯气氧化再生后返回使用。
A new method of antimony white production from antimony sulfide ore using acidic solution ofantimony pentachloride as lixiviant was reported. This method contains such processes as leaching, re-duction, hydrolysis, neutralization, and regeneration of lixiviant. The quality of antimony white ob-tained by this method corresponds to the quality stundard of 0~# antimony trioxide of the People's Re-public of China. The lixiviant can be returned to the use in leaching process after oxidative regenerationby chlorine.
