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

However, this process is based upon density alone and should not be confused with the process of froth flotation. Thus, the process of froth flotation is not solely dependent upon the density of the material; it is also dependent upon its hydrophobic nature. For example, froth flotation is a technique commonly used in the mining industry. In

2010-08-06· Froth flotation is an adaptation of a beneficiation process long used in the mining industry. Froth flotation requires the addition of a chemical to stabilize the froth, which is mechanically formed by “beating” air or gas into the water. Froth flotation is less sensitive to overloading than dissolved gas flotation; however, it has other shortcomings. These may limit the application of
