Froth Flotation Handbook
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 ...

Flotation | SpringerLink
Flotation. According to the difference in physicochemical properties of mineral particle surfaces, flotation is the method that selectively enriches the target minerals in the pulp at the gas-liquid interface and separates them from the pulp, thus realizing the mineral separation. It is also known as floating separation.
