  • Selective separation of gold from iron ore samples using ...

    Abstract. Gold in iron ore samples is separated from iron (major matrix cation), antimony and vanadium using anion exchange resin in (0.2 M) HBr, potassium peroxodisulfate and acetone:water:nitric acid media. The exchangeable anion Cl − of the ion exchanger Dowex 1X 4 is replaced by Br − using (6 M) HBr solution.
