There are more than 20 types of mineral flotation. Universal separation method, because by using flotation can be separated almost all minerals. It is used for all types of ores and minerals (chalcopyrite, molybdenite, galena, sphalerite, gold, talc, mica, carbon, rare earth mineral, uranium minerals, and others).

The model allowing to describe correctly kinetics and speed of flotation of raw mineral material of any kind are proposed. The model take into account delay in extraction of a component in concentrate, upper limit of component’s extraction, inclination of e(t) parameter* and can be considered as universal analytical tool for investigation of kinetics and speed of flotation. It is recommended to use the model for optimization of technological schemes and algorithms of control of flotation.
