Zusammenfassung:The invention discloses a method for producing antimony with antimony oxide powder. The method comprises the following steps of a. introducing a reducing gas into the antimony oxide powder, heating to carry out reduction reaction, and reducing the antimony oxide powder to metallic antimony to obtain a metallized solid product; and b, smelting the metallized solid product obtained in the step a to obtain crude antimony and slag. According to the method for producing the antimony with antimony oxide powder, gas is adopted as a reducing agent to reduce the antimony oxide powder, harmful gas such as SO2 and NOx is not generated in a production process, and the method is an environment-friendly smelting method and has a high antimony direct recovery rate. 本发明公开了一种锑氧粉生产锑的方法,其包括如下步骤:a、向锑氧粉中通入还原气体,加热发生还原反应,将锑氧粉还原为金属锑,得到金属化固态产物;b、将所述步骤a得到的金属化固态产物冶炼,得到粗锑和炉渣。本发明的锑氧粉生产锑的方法,采用气体作为还原剂还原锑氧粉,生产过程中不产生SO2、NOx等有害气体,是一种绿色环保的冶炼方法,并且具有较高的锑直收率。
