SK
(B) Carbonate ores
NO
RE
(C) Sulphide ores
(D) Sulphate ores​

Answer 1

Answer:

C) Sulphide ores

Explanation:

Froth floatation is based on the principle of the difference in the wetting properties of the ore and gangue particles with the water and oil. This method is used for those metals whose ore gets preferably wet by the oil and the gangue by the water. The sulphide ores get preferably wet by the oil and the gangue with the water.
