<p>The present invention is related to the mining industry and the industry for treating minerals or materials that contain manganese. More particularly, the invention refers to a process for dissolving and electro recovering manganese dioxide with the same electrolytic cell, which performs both actions with the same energy. The patent particularly refers to a process for improving the speed for extracting manganese from minerals or other materials containing the same, using ferrous ions, such as the direct electro recovery of manganese dioxide from the aforementioned dissolution. The invention consists in a dissolution subjected to an electro-reduction in the cathodic compartment so as to regenerate ferrous ions acting as reducer agents for the mineral phases that contain the manganese. In the preferred embodiment, the electro-oxidation of the manganese dioxide by lixiviation is performed in the anodic compartment of the same cell, being separated in compartments by an anionic membrane.</p> |
