Gravity separation is a method used to separate different materials based on their densities. It relies on the principle that heavier particles will settle faster than lighter ones when subjected to a gravitational force. This technique is commonly used in mining to separate valuable minerals from waste rock. In gravity separation, various equipment like shaking tables, spiral concentrators, and jigs are employed to enhance the separation process. The materials are usually fed into a system where they are subjected to vibrations or water flow, allowing the denser materials to sink while lighter materials are carried away.
