Selective Preconcentration of Gold from Ore Samples

A simple and selective method has been developed for preconcentration of gold in ore samples. The method is based on use of N, N-diethyl-N#x2019;-benzoylthiourea (DEBT) as selective chelating agent and Amberlite XAD-16 as solid sorbent. Sorption behavior of gold with DEBT impregnated resin under optimized conditions has been studied in batch process. The gold ion capacity of the impregnated Get price
