Which one of the following ores is best concentrated by froth–floatation method?

Options

  1. ACassiterite
  2. BGalena
  3. CMalachite
  4. DMagnetite

Correct answer

B. Galena

Step-by-step solution

Froth–floatation is used to concentrate sulphide ores [Galena (PbS)].Cassiterite S n O 2 and Magnetite F e 3 O 4 are oxide ores and Malachite C u O H 2 . C u C O 3 is carbonate ore.
