Jul 16, 2018· The process of removal of gangue from powdered ore is called concentration or ore dressing Hence, it is the essential process in the extraction of metal from its ore because it convert’s the impure ore to pure concentrated ore (ii) An electromagnetic wheel is used in the magnetic separation process of ore from gangue Answer:.

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 61, 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.

Magnetic Separation

1354 Magnetic Separation Magnetic separation takes advantage of natural magnetic properties between minerals in feed The separation is between economic ore constituents, noneconomic contaminants, and gangue Magnetite and ilmenite can be separated from their nonmagnetic rock-forming minerals of host rock as valuable products or as contaminants.
