Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

Effect of H2O2 on the Separation of Mo-Bi-Containing Ore ...

A high flotation recovery of bismuth is undesirable for the final molybdenum flotation concentrates because smelters would not pay for excessive bismuth levels on molybdenum concentrates. Besides, it is uneconomic and inefficient to remove or recover Bi from the Mo concentrate during hydrometallurgy.
