Froth Flotation Handbook. What is Flotation. Flotation, as the term is applied to ore concentration, means the separation of one of the constituents of an ore from the remainder by causing it to float at or above the surface of a pulp consisting of the finely pulverized ore and water. Minerals that float. Minerals that float have a metallic ...

Abstract. Few of the metals or minerals required by modern civilisation are mined naturally pure and ready to use. Instead they occur in complex aggregates of up to twenty different minerals of which only one or two will be of value. There are some two hundred of these 'value' minerals amoung the several thousand minerals that go to form ...

Flotation Frothers – Frothing Agents. The next reagent that is added is the Flotation FROTHER. The frother strengthens the surface tension of the air that is injected into the flotation cell. As the air rises in the shape of bubbles, they come into contact with the mineral laden collector which attaches itself to the air.
