Abstract

The extractive concentrating of Pt and Au from chloride solution and leaching pulp by solid extractants on the basic of quaternary ammonium iodide, TOPO and TBP has been studied as a prior stage of determination of these elements by XRF and NA methods. The optimal conditions for complete isolation of Pt and Au by SE are recommended. The accuracy of the technique was checked using different reference materials. The results agreed within 10%.
