  • SIMULTANEOUS OPTIMIZATION OF FLOTATION COLUMN

    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.Flotation stabilization and optimization SAIMM,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.
