| Abstract: | The sorption of AuCl4- from chloride solution on synthetic and natural magnetite powders was investigated by batch-sorption experiments. The effects of different parameters on the recovery were studied. The results showed that Au uptake by magnetite was influenced by pH, contact time, chloride concentration, and initial Au concentration. Gold (Au) uptake by synthetic and natural magnetite was at a maximum at pH 6-7 with sorption amounts of 4.4 μmol/g and 5.0 μmol/g, respectively, after 24 hours at an initial Au concentration of 0.05 mol/m3. The SEM-EDX and BSE analyses of the magnetite particles after treatment confirmed the presence of Au precipitates on the Fe3O4 surface. |
