| description | Provided is a method of economically recovering manganese from low-grade minerals and manganese-containing waste. Iron-reducing bacteria and a manganese-containing substance to be treated are mixed in a treatment solution containing trivalent iron ions, the trivalent iron ions are reduced to divalent iron ions by means of the iron-reducing bacteria, manganese ions are leached from the treated substance into the aforementioned treatment solution with the divalent iron ions as reducing agent, the obtained leachate is solid-liquid separated, the manganese ions contained in the separated liquid are insolubilized (solidified) mainly as oxides, and the obtained manganese oxides are precipitated, separated, and recovered.
L'invention concerne un procédé pour récupérer de façon économique du manganèse à partir de minéraux de basse qualité et de déchets contenant du manganèse. Des bactéries de réduction du fer et une substance contenant du manganèse devant être traitée sont mélangées dans une solution de traitement contenant des ions fer trivalents, les ions fer trivalents sont réduits en ions fer divalents au moyen des bactéries de réduction du fer, les ions manganèse sont lixiviés à partir de la substance traitée dans la solution de traitement mentionnée ci-dessus avec les ions de fer divalents comme agent réducteur, le lixiviat obtenu est soumis à une séparation solide-liquide, les ions manganèse contenus dans le liquide séparé sont rendus insolubles (solidifiés) principalement en tant qu'oxydes, et les oxydes de manganèse obtenus sont précipités, séparés et récupérés. |
