flotation cells mineral processing process control

Flotation control Flotation is the most widely used process for extracting minerals from their ores. Although the process was developed as long ago as the early 1900s, flotation remains one of the most complex mineral processing operations. Flotation challenges Optimization and stabilization In flotation

    Flotation is a difficult process to run efficiently. One way to make flotation performance better is to improve cell level control. However, controlling pulp levels in flotation cells is a complex control task because of strong interactions between the levels in flotation cells. Therefore advanced controllers are needed to give good level control

    Jan 20, 2021 The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles
