In the worldwide production of refined metals, it has not been possible to solve the main problems of the industry, which are associated with the high cost of operation, high initial investments, processes that are polluting and the decreasing quality of natural deposits. The present process comprises the anodic dissolution of minerals in cells equipped with ion-exchange membranes at a potential that allows for the dissolution and/or regeneration of the metal salts present in the anolyte and simultaneously the electrodeposition of the metals in the catholyte. This process offers a lower-cost alternative to the traditional processes, avoids negative environmental impact and allows for the recovery of economically valuable by-products.
