• On the extraction of gold(III) with dibutyl carbitol

     · Extraction of HAuCl4 with diethylene glycol dibutyl ether (dibutyl carbitol) was studied in the gold(III) concentration range 10−6− mol/L at cHCl = 1 mol/L and T = 25°C, distribution ratios were determined. Experiments were made at other cHCl. A unified extraction isotherm was obtained with the use of activity coefficients of HAuCl4. The main extraction .

    To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravellike material then enters rotating drums filled with steel balls.
