Abstract: Disclosed herein are various inventive methods and apparatus related to removing magnetic materials from a liquid solution utilizing an apparatus employing a conveyor belt. The conveyor belt may have a forward run moving in a forward direction from a first pulley to a second pulley and a rearward run moving in a rearward direction from the second pulley to the first pulley. The apparatus may include a longitudinally extending magnet housing interposed between the forward run of the conveyor belt and the rearward run of the conveyor belt and interposed between the first pulley and the second pulley. At least one longitudinally extending magnet may be substantially sealingly enclosed in the magnet housing.
