Froth Flotation Process - Mineral Processing & Metallurgy

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.

Metallurgical Accounting Formulas | Concentration and ...

Recovery % Represents the ratio of the weight of metal or mineral value recovered in the concentrate to of the same constituent in the heads or feed to the process, expressed as a percentage. It may be calculated in several different ways, depending on the data available. By assays f, c and t only: R = 100 c(f — t)/f (c — t) = recovery %
