| titleOfInvention | Antimony and purification method thereof |
| abstract | Metal antimony having a low content of these impurity elements is efficiently obtained from a metal antimony raw material containing impurity elements such as arsenic, selenium and iron. In a method for purifying metal antimony, wherein metal antimony containing at least one element of arsenic, selenium, and iron is used as a raw material, and at least one of sodium carbonate and sodium hydroxide and sodium nitrate are used as the raw material. Is heated and melted, and preferably sodium nitrate is further added. More preferably, the step of solidifying molten antimony from which flux dross on the melt surface layer portion is removed to obtain melt-treated antimony, the step of removing solidified flux dross adhering to the surface of the melt-treated antimony to obtain surface-treated antimony, the surface treatment Etching antimony with aqua regia solution. [Selection figure] None |
