A method of removing iron from waste slag from a steel producing furnace that reduces the size of the waste slag to slag particles in a reduction zone. The slag particles are advanced along a conveyor in a first direction. A first and second magnet are positioned adjacent the conveyor to remove slag particles that have a sufficient iron content to be attached by the first and second magnets. A first removal belt is advanced between the first magnet and the conveyor to remove slag particles removed from the conveyor by the first magnet. A second removal belt is advanced between the second magnet and the conveyor to remove slag particles removed from the conveyor by the second magnet. A first and second separation screens are positioned along the conveyor to remove particles not removed by the first or second magnets that are small enough to pass through the first and second separation screens.
