Abstract

A column flotation cell is an industrial process used to recover mineral species of interest from the pulp of ore. The adoption of these cells by the mining industry is already a reality due to multiple advantages (lower cost of operation, less space occupation, substantial reduction of energy consumption and lower consumption of reagents) and it has motivated the interest of the scientific and industry world with the purpose of improving and optimizing this productive process. Despite the advances in the literature regarding the modeling of the process for control and optimization purposes, it is observed that models that are usually presented lack a profound variables interaction study and, in addition, practically all of them only analyze the steady-state operation without considering the dynamic behavior of the system. In this context, this paper presents a complete and compressive modeling and multivariable analysis of this process, providing important information for control purposes.
