Smelting Stibnite For Antimony

Oxidizing Roast; Stibnite the Antimony Mineral

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, roasting-reduction is of greater importance than precipitation.

ing of antimony bullion obtained by smelting gold- and silver-bearing ore from the Yellow Pine mine at Stibnite, Idaho, and decided that, of the various electrolytes studied, the antimony fluoride-sulfuric acid solution was the most satisfactory.

Stibnite - Wikipedia

Stibnite has a structure similar to that of arsenic trisulfide, As2S3. The Sb(III) centers, which are pyramidal and three-coordinate, are linked via bent two-coordinate sulfide ions. However, recent studies confirm that the actual coordination polyhedra of antimony are in fact SbS7, with (3+4) coordination at the M1 site and (5+2) at the M2 site.

Jul 17, 2012 · In general the lowest grades of sulfide ores containing 5–25% antimony are volatilized to antimony trioxide: 25–40% antimony ores are smelted in a blast furnace: and 45–60% antimony ores are treated by liquation or iron precipitation.

Antimony Smelting - Mineral Processing & Metallurgy

Antimony Smelting. The history of the antimony industry of China dates back to 1897 when the Tai Shing Co. was formed, under contract with the Hunan Bureau of Mines, for the smelting of the ore to crude; and in 1908 the Wah Chang Mining & Smelting Co. was formed for the smelting and refining of the ore and crude to regulus.

Extraction of Antimony

Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation, whereby the fusible sulphide is removed from the gangue and concentrated. The concentrate is then reduced to metal by smelting with wrought iron in pots, in reverberatory furnaces or sometimes in blast furnaces,

Recoveries of un-oxidized sulfides can be in the mid 90% range with concentrate grades of 60 to 68% for stibnite ores. The stibnite concentrates are then fumed to a crude oxide that is either fumed to a finished oxide or reduced to metal and then fumed to finished oxide. Tetrahedrite concentrates are usually leached in alkaline solutions that are electro-won to recover antimony metal or oxidized to sodium …
