gold recovery in sb concentrates

  • doctoral thesis DiVA portal

    Alkaline sulphide solution was used to dissolve antimony from the concentrates. Antimony recovery from tetrahedrite dissolution was increased by approximately 280% when the reaction temperature was increased from 84϶C to 105϶C. By raising the concentration of Na2S from 60 g/L to 100 g/L, the extraction of Sb was.

  • Process Flow Sheet for Gold and Antimony Recovery from Stibnite .

    Dec 20, 2017 . Recovery of gold from refractory ores requires a pretreatment to liberate the gold particles from the host mineral. In particular, in the case of stibnite (Sb2S3), the antimony (Sb) forms stable compounds with sodium cyanide (NaCN) during the cyanidation process; as a consequence, cyanide consumption.
