The lonely element Antimony | Periodic Table | ChemTalk
At low temperatures, the element separates from a stibnite concentrate through smelting. By using iron oxide as a reducing agent, sulfur goes through a fixation smelting process in sodium molten salt. This effective method can recover up to 91.48% antimony with a purity of 96%. Sodium sulfide leaching can isolate antimony from refractory gold ore.
