Abstract:
     Being characterized by using sbc15 as chlorinating agent, the process can effectively, economicaly and reasonably produce GB4062-82 No 1 or No O antimony white from antimony sulfide ore through following wet processes as lixivation, reduction, hydriyzation, neutralization and regeneration of chchlorinating agent etc. The method is known as low cost, good economic efficiency and operation flexibility, no pollution to environment as well as short process flow, it is suited to process antimony sulfide ore bearing Sb is larger than 20, As is not larger than 0.5 and Pb is not larger than 0.5 (in pts. wt. ) or antimony sulfide concentrate.
