Abstract
Recovery of silver and similar metals from liquids containing such metals. These liquids which then also contain sticky or gel-forming substances which tend to clog the recovery apparatus are led through it, the apparatus including a filter container (5) with a granular filter material (14), the metal containing liquid being introduced at the bottom of the filter container under the filter material (14). A waste trough (20) is arranged round the upper end of the container (5) such that the upper wall portion of the filter container (5) such that the upper wall portion of the filter container (5) constitutes a wall of the waste trough (20). The filter material only occupies a portion of the filter container (5). Compressed air from a compressed air pipe (16) is supplied when necessary to an outlet nozzle (15) at the bottom of the filter container, and this compressed air flows upwards through the filter material (14) to break up lumps and the like of the sticky or gel-forming substance for entraining it and taking it over to the waste trough (20).
