Which of the following involve the froth flotation process?
Hint: To answer this question, you should recall the concept of the froth flotation process. This process is used for mineral beneficiation. In ore/mineral beneficiation, froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth layer.
