<p>A method for treating wastes from working ferromagnetic materials is proposed. In this method, the wastes are mixed in a first vessel (13) with a washing solution, and the oil or the oil-water emulsion adhering to the wastes is dissolved. In this vessel (13), the ferromagnetic constituents of the wastes are then separated by means of a magnetic field produced by external magnets (14), and the further constituents are subjected to a second washing step in the next vessel (20, 49). The ferromagnetic constituents are fed to a further parallelly arranged vessel (21, 42) and likewise subjected therein to a second washing step. The separated and deoiled constituents can then be filtered out of the appropriate washing liquids in suitable filter devices.</p> |
