Removal of Arsenic from Alkaline Process Water of Gold Cyanidation by Use of Functionalised Magnetic Adsorbents
In this study, three types of functionalised magnetic adsorbents, namely Fe3O4@SiO2@TiO2, γ-Fe2O3@ZrO2 and Fe3O4@CeO2/Ce(OH)4, were synthesised and used to extract arsenic species from alkaline gold cyanidation process waters. A series of analytical methods were employed to comprehensively character...

| description | In this study, three types of functionalised magnetic adsorbents, namely Fe3O4@SiO2@TiO2, γ-Fe2O3@ZrO2 and Fe3O4@CeO2/Ce(OH)4, were synthesised and used to extract arsenic species from alkaline gold cyanidation process waters. A series of analytical methods were employed to comprehensively characterise the synthesised adsorbents. In addition, systematic adsorption tests were carried out to determine their adsorption behaviour towards both As(III) and As(V) under alkaline conditions, as well as regeneration and reuse of the synthesised adsorbents. |
