  • Antimony Smelting - Mineral Processing Metallurgy

    China now leads the world in antimony production, having contributed during recent years something over 60 per cent, of the world’s production. 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 metallurgy of antimony - ScienceDirect

    17/07/2012  1. Background. Antimony is a silvery, white, brittle, crystalline solid that exhibits poor conductivity of electricity and heat. It has an atomic number of 51, an atomic weight of 122 and a density of 6.697 kg/m 3 at 26 °C. Antimony metal, also known as ‘regulus’, melts at 630 °C and boils at 1380 °C.

  • How to Remove Arsenic, Antimony Bismuth from Copper

    Removal of arsenic, antimony and bismuth from copper may take place in the smelting operations by scorification, volatilization, or, under special treatment, by processes of concentration. Owing to the great variety of materials that are treated in economical metallurgy, it is rarely possible to obtain exact weights from any particular operation.

  • Lead smelting - Wikipedia

    The Roman lead smelting has led to evidence of global pollution. Greenland ice cores from 500 BCE to 300 CE show measurably elevated lead content in the atmosphere. In the USA there are 400 forgotten lead smelting firms that operated in the 1930s to 1960s and may have deposited dangerous levels of lead contamination in nearby soil.

  • REDUCTION SMELTING OF ANTIMONY CONCENTRATE

    The formation of metallic antimony occurred without any decomposition in the course of the direct reduction of sodium metaantimonate. The concentrate reduction smelting carried out in presence of a refining flux provided to obtain rough antimony of low impurities content. Keywords: antimony concentrate, reduction smelting, rough antimony.

  • 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 ...
