    Generally, the metal particles of the ore are heavier than the impurities. So we use the principle of gravity separation to separate the two. Here crushed ore is mixed with an upward stream of running water. The lighter particles of the gangue wash away in the running water. The heavier metal particles settle down and can be separated easily.
