When the densities of the ore particles and gangue particles are different, then the ore is concentrated by

Solution

The concentration of ore:
The removal of gangue particles from ore, also known as ore concentration, is done to increase the quantity of metal in the ore.
Different processes are used to concentrate ore.
They are based on the type of ore, the density of ore etc.
Levigation:
Levigation is a method of concentrating metallic ore and gangue particles by employing the density difference between the ore and the gangue particles.
During the levigation process, the powdered ore is treated with a stream of running water.
The rush of water washed away the lighter gangue particles, leaving the heavier ore particles behind.
It's useful for separating oxide ores.
