Dec 01, 2003· The high abundance of iron in iron ore samples causes serious interference in gold determination, whatever the used analytical method is; so gold separation prior to determination is a necessary step. The aim of this work is to separate gold from iron rich samples for spectrophotometric determination.
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.
