Abstract
► We separately recover Au and Pt in the metallic state by coprecipitation with Fe(II) hydroxide. ► Au(III) is stoichiometrically and rapidly reduced to metallic Au in acidic solution prior to coprecipitation. ► Pt(IV) is conversely reduced to Pt(II) and metallic Pt only after coprecipitation. ► Pt(II) can be also reduced to metallic Pt after coprecipitation.
