Answer 1

Answer:

Three methods of concentration of ores are:

1. Concentration or centrifugation on the basis of difference of densities: This method is used when there is large difference in densities of ores and impurities.
2. Froth floatation method: This method is used for the concentration of ores of the metals whose ores are in sulphide form.
3. Magnetic separation: This method is used when either of ore or the impurity have some magnetic properties.
