Hydraulic Washing. This method is based on the differences in weight between the gangue and the metal. 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.

Explanation: Concentration by hydraulic washing requires the ore particles to have a higher mass compared to its gangue particles. Hydraulic washing can be used for oxide ores of iron and tin such as haematite and tinstone and also for native ores of silver and gold. Pyrolusite is concentrated by magnetic separation.
