SIMULTANEOUS OPTIMIZATION OF FLOTATION

2016-5-17 · The performance of the flotation column is determined by grade and recovery, but a key determinant is the optimization of the parameters that constitute the flotation operation. Optimization guarantees that the column operation reaches the reference values necessary for the desired recovery and grade of the concentrate stream. According to previous investigations, GA is a powerful tool for optimizing the complex processes such as the flotation column. The metallurgical performance of the column flotation is a function of a broad group of variables present in flotation: chemical dosage, gas holdup, froth height, feed characteristics, solids content, and air, and wash water flow rates, etc., Therefore, the knowledge of the independent variables should be useful at the time of optimizing and controlling the operation of the flotation
