Gravity separation is a method used to separate different materials based on their densities. It relies on the force of gravity to pull heavier particles down while lighter ones remain suspended. This technique is commonly used in mining to separate valuable minerals from waste rock. In addition to mining, gravity separation is also applied in recycling and waste management. For example, it can help separate metals from plastics or other materials. Techniques such as jigging, shaking tables, and spiral concentrators are often employed to enhance the efficiency of this separation process.
