Froth floatation:

  1. is a physical method of separating mineraal from the gangue
  2. is a method to concentrate the ore depending on the difference in wetability of gangue and the ore
  3. is used for the sulphide ores
  4. is a method in which impurities sink to the bottom
Correct Answer: Option(b)(c)(d)
Solution: Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. Flotation has now become the most widely used process for extracting many minerals from their ores.Generally sulphide ores are concentrated by "Froth floatation" and cinnabar(HgS) is a sulphide ore
