Froth flotation is a complicated process which is difficult to establish its first-principle model. Due to the fluctuations in the grade of raw ore, adaptively adjusting the set-points is extremely important in the flotation process. The inappropriate set-points easily lead to the instability of the process. This paper presents a fuzzy association rule-based …

Improved flotation operation can be achieved by improved control in terms of stabilization, regulation and optimization of the plant. Through stable operation, the performance of the plant is observed without being obscured by the effects of disturbances and fluctuations. This allows for the optimum conditions to be easily identified.
