• Flotation ore dressing Britannica

    Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century toFloatation Separation, Mining Flotation Process, Flotation,Floatation Separation. Floatation is a main method to separate the ores by the different natures of wetting by water. The hydrophobic mineral will be gathered on the bubbles and floats on the surface. However, the hydrophilic minerals will stay in the water. Applies for the following ores:
