摘要： The invention relates to a process that allows electrolytic copper cathodes to be produced, using the pregnant leach solution (PLS) directly in the electrowinning, avoiding the step of mineral concentration by solvent extraction. Furthermore, this process has a modular structure and the full process can be mobilised depending on the requirements of the process itself. The invention also relates to the system that operates with the previously described process.

摘要： The invention relates to an EWS module device for electro-winning and/or electro-refining, based on a saturated leaching solution of PLS/electrolyte/raffmate/ILS without solvent extraction, characterised by comprising: a tank (10 and 12); a set of electrolytic cells contained within the tank, wherein the cells are electrically and volumetrically separated by the internal walls of the module (14), with the cells being connected in series by a joining board or capping board (3); an intercellular bar (1); an intercellular bar guide (2); inlet and outlet ducts for the PLS/electrolyte/raffinate/ILS (17) and (11) for each cell independently; and each EWS module is in turn connected to the other modules by an inter-module connector (18), and same in turn control the connection and disconnection of the EWS modules by an interrupter (25); operating process of the EWS module device; and connection and disconnection process between different EWS module devices.
