Modeling of Flotation Process—An Overview of Different Approaches
An overview of the literature indicates that various approaches have been adopted in quantifying the process. Flotation models based on kinetics have prevailed in almost all flotation conditions regardless of the ore type and ore characteristics as well as flotation cell configurations. It may be concluded that the classical first-order kinetic ...
Flotation as a Separation Process
Without this process, many familiar metals and inorganic raw materials would be exceedingly scarce and costly because the high-grade ores that could be processed by simple physical and mechanical methods have long since been used up (1). Flotation initially originated from the field of mineral processing, usually termed froth flotation.
