[0039] Then, due to the strong magnetic field emitted by the magnet 7, an induced magnetic field is generated inside the metal ore, which is attracted to the magnet 7. When the mixture of ore and stone passes through the magnetic field, the magnetic stone particles are attracted to the magnet, and the ore directly falls down, achieving primary separation. The mixture of ore and stone that is not attracted in the separation machine body 1 continues to descend and passes through the screen surface. The ore particles smaller than the screen hole size fall through the screen hole, while the stone larger than the screen hole size is intercepted on the screen surface, thereby achieving secondary separation.
