  • Improved gold and silver extraction from a refractory

    Similarly, gold extraction improved from 49% to 55–78% after the pretreatment. The highest extraction of silver (87%) was recorded to occur with 4.1 mol/L Na 2 S and 2.0 M NaOH . The extraction of silver and gold tended to improve with increasing the concentration of Na 2 S at fixed concentrations of NaOH . It can be inferred from these

  • 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, Sb 2 S 3 + 3Fe =2Sb + 3FeS The reduction in

  • Improved gold and silver extraction from a refractory

    Improved gold and silver extraction from a refractory antimony ore by pretreatment with alkaline sulphide leach. Cyanide leaching of the ore consistently resulted in low extraction of gold (49%) and silver (18%) confirming the refractory nature of the ore. Alkaline sulphide treatment of the ore under suitable conditions was shown to leach out up to 85% Sb, which remarkably improved the
