How Antimony is Processed by Flotation
The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore. The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of quartz but contains, in addition, a …

Beneficiation of antimony oxide ore: A review | SpringerLink
Antimony oxide ore beneficiation has become one of the world's largest mineral processing conundrums. In recent years, many experimental studies dealing with antimony oxide ore have been carried out, resulting in new technical achievements. Much attention has been paid to improving the mineral processing technology of antimony oxide based on such ...

The metallurgy of antimony
This process consisting of heating molten antimony sulfide in crucibles with slightly more than the (6) Sb 2 S 3 + 3Fe → 2Sb + 3FeS theoretical amount of fine iron scrap, depends on the ability of iron to displace antimony from molten antimony sulfide. Sodium sulfate and carbon are added to produce sodium sulfide, or slag is added to form a light fusible matte with …

Metallic antimony with a purity of 99.4% is obtained when the antimony oxide is reduced in a reverberatory furnace at 1200°C by reducing coal. During the refining process in a reverberatory furnace, any As accompanying the antimony oxide is removed by the addition of sodium hydroxide. AAR is generated during the As removal process.
