What is Concentration of Ore? Definition, Physical

4/10/2019· In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use. The ore can be concentrated or separated by both physical and chemical means. The ore obtained after the completion of the ore concentration is called concentrate.

Concentration of Ores Study Material for IIT JEE

This method of concentration of the ore is based on the difference in specific gravities of the metallic ore and gangue particles. Generally metal ores are heavier than the gangue associated with them. By flowing the powdered ore in a current of water, the lighter rocky impurities can be washed away and the ore particles are left behind.

Electromagnetic separation is employed for the

Electromagnetic separation. A process of removing magnetic materials from relatively nonmagnetic materials, using electromagnets which travel along a conveyor, over a drum, or into a revolving screen. So, from gangue and ore, one of them must be a magnetic material and other must be non-magnetic. Option D is correct.

What type of ores can be concentrated by magnetic

The ore which can be attracted by the magnetic field can be concentrated by the process of magnetic separation. Among the ores mentioned in table 6.1, the ores of iron such as haematite (Fe 2 O 3), magnetite (Fe 3 O 4), siderite (FeCO 3), and iron pyrites (FeS 2) can be separated by the process of magnetic separation.
