The Shaking Table separation is operated by the force between deck water flow and transverse water flow. The riffles or the grooves in the deck is longitudinal which is vertical with the direction of water. When the water flows, it will cause the swirling The force caused by water swirling and deck pulsation will loosen the ore sand layer and the different minerals will be separated as the different density. The heavier mineral will fall down, and the lighter one will be raise up. So the concentration is operated.
