Principles of Froth Flotation | SpringerLink
To achieve selective flotation of mineral particles, whether by their removal in a froth or by the less-used method of agglomeration, specific characteristics of one or more of the mineral species present must be adequately developed. Provided these produce sufficiently marked differences of behaviour in the presence of air, they can then be exploited. If a particle is to be held in a ...
