MoreConcentration of Ores - Class 12 Chemistry MCQ - Sanfoundry
Explanation: Electrostatic separation is a method used for concentration or separation of ores when they are good conductors of electricity. It is based on the principle that when an electrostatic field is applied the ore particles, which conduct electricity, get charged and get repelled by electrodes having same charge and all thrown away.

Extraction of Metals from Ores – Different Processes Involved
The ground ore particles are carried on a conveyor belt with two wheels. One of these wheels is magnetic. The ferromagnetic ore particles will then get attracted and separated from the impurities easily. Froth Floatation: This is one of the methods of extraction of metals from ores by using two mediums together.

Concentration of Ores - Toppr
So nearly all rocks on the planet have some metal or mineral content. However, the concentration of this metal is too less for it to be valuable. Ores usually have a very high content of the desired mineral, but it still must be separated from other mixed impurities, This method is known as the concentration of ores.

The method used for the concentration of sulphide ores is:
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. The principle of froth flotation process is that sulphide ores are preferentially wetted by the pine oil, whereas the gangue particles are wetted by the water. Hence the method used for the concentration of sulphide ores is froth flotation.
