Extraction of antimony

May 17, 2021 Selectivity of sorption matrices increases with increasing solution acidity and with an increase in the concentration of hydrogen phosphate groups in the composition of the material. Having enhanced affinity for negatively charged antimony(III) ions, titanium(IV) oxyhydroxides are potentially attractive for extraction of anionic species

  • Extraction of Antimony
    Extraction of 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

    Jun 01, 2004 Antimony extraction is more effective in chloride concentration range of 1.2 to 2.5 M. To reduce this extraction, the chloride concentration in the aqueous solution should be adjusted to below 1.2 M or higher than 2.5 M. To minimize the antimony extraction, the acidity of the aqueous solution should be kept as low as possible
