Metal production processes carried out in electrolytic cells release gases into the environment, that contain microdrops of the components of the electrolyte, from which the metals are produced, one of said components generally being an acid or a strong base. The difficulties created by said gases containing microdrops are varied and affect the operators, structures and production equipment. The operators must therefore use masks to protect their respiratory system and wear glasses to protect their eyes. The structures are attacked by corrosion, as is the equipment required for the process and the handling of inputs and products. The measures currently adopted to mitigate the problems consist in placing polypropylene spheres on the surface of the electrolytes or incorporating surfactants, thereby creating problems in the extraction process by means of solvents, and installing extraction systems in the bay or in the cells, which, in turn, generate other problems given that the surface of the cell remains in contact with the environment. The invention consists in confining the region on the free surface of the electrolyte in a compartmental manner by inserting an anodic confinement element over each anode, with lateral flexible skirts that seal over the vertical faces of both electrodes when the cathodes are introduced into the cell, wherein the ends of the confined space face the openings of perforated extraction ducts arranged on both sides of the cell or of an anode and cathode supporting structure introduced into the cell, said ducts connecting to the normal extraction system of the production bay, thus preventing the gases from reaching the surroundings. |
