Bubble size is believed to be closely related to flotation performance and responds to changes in the reagent dosage, probability density function of bubble size based feedback predictive control for reagent dosage is proposed.
- •
Moreover, in order to eliminate the change of condition of given ore such as ore grade and handling capacity during flotation running, a fuzzy theory based feedforward compensator will be used to calculated the reagent dosage in advance according to ore grade and handling capacity.
- •
So, a combined fuzzy based feedforward (FBF) and bubble size distribution (BSD) based feedback reagent dosage control strategy is proposed to implement the product indices in copper roughing process.
