Abstract: A method and unit for the separation of non-ferrous, ferrous and non-metal portions in bulk material handling, particularly for the recycling of materials for subsequent use, wherein the method comprises: the application of eddy currents for the separation of portions of non-ferrous and conductive materials that jump with respect to portions of the remaining material stream; the detection of metals in portions of materials by means of an analysis of the metals using electromagnetic sensors, and the separation of said metals by mechanical expulsion means, achieving the separation of metallic material portions, such as stainless steel, and others from the portions of non-metals. The unit comprises a first conveyor belt of the portions and eddy current (Foucault) separators, while a second conveyor belt includes electromagnetic metal sensors and selective expulsion means which are controlled by said electromagnetic metal sensors.
