Lost recovery in the flotation circuit results in lost revenue


We start the optimization process by understanding your process goals. Our flotation experts can measure characteristics such as bubble size, bubble load, superficial gas rate (Jg), froth stability / transportation / depth to identify possible avenues for improving flotation cell performance.

This information, along with detailed surveys and historical operating data are used in modelling and simulation techniques. These techniques, together with extensive industrial and consulting experience and database are used to evaluate existing or new operations, and highlight opportunities for improvement in performance.

The models can also be used to evaluate disturbances to the circuit tonnage, changing the feed ore type or changing the reagent addition rates to the circuit. Once an improvement area is identified, we work with you on the design and implementation of the proposed changes.

The performance of the flotation circuit is often strongly influenced feed size from comminution circuits. Metso experts can determine the relationship between grind size and the flotation grade-recovery performance for your operation and determine the optimum trade off between grind size and flotation recovery.
