The results showed that Gold (Au) uptake by magnetite was influenced by pH, contact time, chloride concentration, and initial Au concentration. Gold uptake by synthetic and natural magnetite was maximum at pH 6–7 with sorption amounts of lmol/g and lmol/g, respectively, after 24 hr at an initial Au concentration of mol/m3.
