Hydraulic washing, Magnetic separation, Froth floatation methods are physical processes of separation of ore articles and gangue particles. Hydraulic washing method depends upon the difference in the specific gravity of mineral and gangue.

Magnetic separation uses a magnet to physically separate magnetic material from non-magnetic.

Froth floatation is also a physical separation process of selective wetting of or particles using oil to make a foam-like material called Froth.

But leaching involves the treatment of the ore with a suitable chemical reagent to make the element into a soluble complex leaving gangue particles insoluble.
