Introduction to Mineral Processing. Froth Flotation. 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.

It becomes so hot that the copper concentrate immediately ignites when it is blown into the furnace along with oxygen and a silica-bearing flux. The silica flux binds with the iron and other impurities and keeps them separated from the copper.Liquid copper and iron fall to the bottom of the furnace like a molten metal rain, while the sulfur combines with oxygen to form sulfur dioxide gas.
