  • Flotationore dressingBritannica

    Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey ParrottSheffer, Research Editor.

  • Model Predictive Control for Froth Flotation Plants

    Froth flotation is a common method to extract a certain type of mineral from ore while depressing the amount of undesired minerals in the extracted concentrate. It is done by adding certain chemical reagents to selectively rendering the desired mineral hydrophobic. In a flotation cell, air bubbles then lifts the mineral.
