Next, the ore enters the Sb concentrate smelting stage. It is then refined, which produces metallic Sb. The M&F stage includes the process of producing antimony-containing products by further processing Sb compounds and Sb alloys (Fig. 1). Sb compounds mainly refer to antimony oxide (Sb 2 O 3), and antimony sulfide (Sb 2 S 3).
