    A Novel Mineral Flotation Process Using Thiobacillus ...

    Flotation is known as one of the methods which can separate minerals on the basis of differences in the mineral surface properties. In the flotation process, mineral particles with hydrophobic surfaces attach to air bubbles generated at the bottom of a flotation column and float up to form a froth at the top of the column.
