Antimony sulfide ore is one of the antimony ore types. In the production, processing and beneficiation will be applied to upgrade the raw materials to achieve its high grade concentrates. Antimony beneficiation flow chart is well arranged. Various types of machines are utilized in the antimony sulfide ore concentration, such as crushing machine, grinding mill, washing plant, filtration equipment, sorting and sizing machine, concentration plant, recovery plant, magnetic separator, flotation machine, antimony ingot making plant etc.
Antimony processing demands high advanced technique. In modern time, numerous technic are developed for extracting antimony from its ores. The technique employed is determined by ore characteristics, for instance, if the ore is a sulfide, an oxide, or a complex ore, as well as on the grade, that ranges broadly from about 1.5 percent to greater than 60 % antimony by weight. The chief techniques utilized consist of volatilization roasting, blast furnace smelting, liquation, reduction, leaching and electrowinning, precipitation, refining and so on.
The antimony metallic manufactured by the primary operations outlined above generally should be refined to achieve commercial purity. Iron and copper levels might be decreased by heating the metal with stibnite or a combination of sodium sulfate and charcoal to make a molten ferriferous matte that is next skimmed from the surface of the metal.
The molten metal is then covered with an oxidizing flux of caustic soda or sodium carbonate to get rid of the arsenic and sulfur. The lead can't be easily taken away from antimony metal; however antimony that contains lead being a contaminant finds ready use in the manufacturing of antimonial lead and lead-based alloys.
