Expert Answer
Magnetic Separation:
1.This is based on differences in magnetic properties of the ore components.
2.If either the ore or the gangue is attractedby a magnetic field, then magnetic separations are carried out.
For example, iron ores.
3.The ground ore is carried on a conveyer belt which passes over a magnetic roller.
4.As the ore particles roll over the belt, the magnetic particles are attracted by the magnetic roller.
5.As a result of this, two separate heaps are formed.
6.The heap below the magnetic roller contains the magnetic particles while the heap formed away from the magnetic roller contains non-magnetic impurities.
7.For example, in case of tinstone, the tungstate,being magnetic forms a heap belowthemagnetic roller while the non-magnetic ore particles formsaheap away from the magnetic roller.
