Abstract

The electrolytic manganese residues (EMRs) contain variable amounts of trace metals and valuable elements, which can negatively impact the environment. This research focused on recovering valuable elements (SO ₄ ²⁻ , NH ₃ –N, Mn, Mg, and Fe) from EMRs by bioleaching. Bacteria (Y1) were isolated from EMRs and then acclimated for bioleaching processes. The bacteria can grow with waste molasses as the only carbon/nutrient source. After bioleaching for 8 days, 78–88%, 85–98%, 75–85%, 88–95%, and 95–99% of SO ₄ ²⁻ , Mn, Mg, Fe, and NH ₃ –N were leached out from EMRs with a solid-to-liquid ratio of 1:2.5 kg of EMR powder L ⁻¹ of leaching liquid. Then, the elements of NH ₃ –N, Mn, Mg, and Fe were separately precipitated as (NH ₄ ) ₂ Mn(SO ₄ ) ₂ 6H ₂ O, (NH ₄ ) ₂ Mg(SO ₄ ) ₂ 6H ₂ O and (NH ₄ ) Fe(SO ₄ ) ₂ 6H ₂ O by adjusting the pH of the bioleachate (i.e., the filtrate of the leachate solution) to 8.5–9.0. The process could be cost-effective due to the use of waste molasses (a low-cost product from sugar processes) as carbon sources and may have a great potential for industrial applications.
