How the magnetic and nonmagnetic imgredients in an ore can be separated? Explain the process involved in it.

Explanation

1.By the magnetic separation method, the megnetic and nonmagnetic ingredients in there can be separated depending on their magnetic properties.
2. This method requires an electromagnetic machine.
3.The main parts of this machine are two types of iron rollers and the conveyor belt moving continuously around them.
4. One of the rollers is non-magnetic while the other is electromagnetic.
5. The conveyor belt moving around the rollers is non-magnetic which is made up of leather or brass.
6. The powdered ore is poured on the conveyor belt near the non-magnetic roller.
7. Two collector vessels are placed below the magnetic roller.
8. The particles of the non-magnetic part in the ore are not attracted towards the magnetic roller.
9. Therefore, they are carried further along the belt and fall in the collector vessel places is away from the magnetic roller.
10. At the same time the particles of the magnetic ingredients of the ore stick to the magnetic roller and therefor fall in the collector vessel near the magnetic roller.
11. For example, cassiterite is a tin ore.
12.It contains mainly the non-magnetic ingredient stannic oxide `(SnO_2)` and the magnetic ingredient ferrous tungstate `(FeWO_4)`. These are separated by the electromagenetic method.
