Offline parameter estimation was used to verify the validity of this model for describing the dynamics of batch froth flotation processes. Statistical methods such as principal component regression and partial least squares regression were used to calibrate the real-time froth surface images against the recovery measured offline.

Determine Froth Flotation Kinetics

Froth flotation of minerals is one of the dominant concentration processes available today. By this process finely divided mineral particles within a pulp separate according to the hydrophobicity of their chemically modified surfaces. Hydrophobic mineral particles are collected and transported from the pulp by air bubbles into the froth along with some hydrophylic particles which are transported by entrainment. In the froth substantial rejection of unwanted minerals takes place with an ...

Basic Principles and Variables Affecting Froth Flotation

The purpose of the oil in froth-flotation is 1 to form together with the water and solid of the pulp and the gas introduced into the pulp a froth; and 2 to aid in the selection of the particles of mineral of metallic resinous or adamantine luster in the pulp from the gangue minerals. Not all oils will perform both of these functions with all ores in all processes. Newly refined paraffin hydrocarbons if pure will not froth to a sufficient extent to make them efficient flotation ...
