    EiC July 2008 Feature Antimony revisited. Antimony lives in the neighbourhood of arsenic and shares similar traits not found alone'.2 Indeed, antimony is usually found as the sulfide ore, stibnite, Sb2S3, 250 years earlier.4 The process involved roasting stibnite to form the oxide, in which stibnite was reduced directly to metallic antimony by reaction with iron.

  • Oxidizing Roast; Stibnite the Antimony Mineral

    2017-4-9 · The leading antimony mineral is stibnite. In smelting stibnite ore two processes are available, precipitation and roasting-reduction. The former is suited, only for high-grade ores. As low-grade ores are more common than high-grade,

  • Extraction of Antimony

    More than three-quarters of the world's supply of antimony ore are obtained from the province of Hunan, China. In France, the ore deposits at La Lucette yield an annual production of 3,000 tons of antimony. About 1,000 tons of antimonial lead, containing 21 per cent, antimony, are also produced annually in Burma.

    The generation ability of liquid phase for mixture of iron ore powders is determined by basicity, roasting time, roasting temperature and chemical composition of iron ores.

  • Smelting and Roasting Ores to recover gold, silver

    2014-6-26 · Heating ores to elevated temperatures is called roasting, and it causes the oxygen in the air to convert the sulfur in the ore to sulfur dioxide, which is a gas and is emitted to the air. The process works best when the ore is crushed to small pieces before roasting.

    2021-5-11 · Antimony is often found in other ores as well, e.g., silver, copper, and lead. The pure element antimony is produced from the ore by roasting it to form the oxide, then reducing the oxide with carbon or iron; often a flux of sodium sulfate or sodium carbonate is used to prevent loss of molten antimony by evaporation.

    2021-4-21 · Antimony can be isolated from the crude antimony sulfide by a reduction with scrap iron. The sulfide is converted to an oxide and advantage is often taken of the volatility of antimony oxide, which is recovered from roasting. This material is often used directly for the main applications, impurities being arsenic and sulfide. Isolating antimony

    2005-1-1 · Oxidative roasting is used extensively to pre-treat base and precious metal-bearing materials and to oxidize iron sulfides to generate sulfur dioxide for fixation with lime or sulfuric acid production. One of the major disadvantages to roasting is the presence of high antimony in the ore. Levels above 0.5% antimony in the Giant Yellowknife
