Processes that take place during extraction of HAuCl4 from hydrochloric acid solutions with neutral oxygen-containing extractants (esters, ethers, and ketones) were considered. Distribution ratios for certain extractants were determined. Separation factors beta(Au/M) (M = Fe, Ag) were shown to exhibit low change upon extractant variation. For example, when D (Au) changes by 6 orders of magnitude, the maximum deviation from log beta(Au/Fe) = 3.5 is not larger than 0.5, average s = 0.2.
