[Mechanism of gold solvent extraction from alkaline cyanide solution by surfactant 1 427].
The solvent extraction of gold and the structure of the organic phase were studied by labelled 198Au, 31P NMR and FTIR spectroscopy. The results show that the water content increased with the increase of gold contents in the organic phase. The P=O stretching decreases, while the 31P signal shifts to upfield.
