Electrostatic separation of minerals from each other is based on their differences in the following property ?
Correct answer: C. Electrical conductivities
- A. Densities
- B. Magnetic permeabilities
- C. Electrical conductivities
- D. Hardness
Explanation
Electrostatic separators charge mineral particles and separate them according to how readily they conduct or retain electrical charge. Therefore, electrical conductivity is the governing property, not density or magnetic permeability.
