| Abstract: | This paper made a study on the separation of gold and iron from leach liquor which contains low concentration of gold and high one of iron,using dibutyl carbitol as extractant in the medium of HCl system.The sponge gold was obtained by counter-current extraction and back-extraction with oxalic acid. The direct recovery and purity of sponge gold were 82.4% and 99.97%respectively The mechanism of gold extraction by dibutyl carbitol and the composition of extract in this system were affirmed by saturated capacity methob, infrared and ullraviolet spectra. |
