Mineral Flotation SpringerLink

The flotation process involves crushing the ore to liberate separate grains of the various valuable minerals and gangue components, pulping the ore particles with water, and then selectively rendering hydrophobic the surface of the mineral of interest. A stream of air bubbles is then passed through the pulp; the bubbles attach to and levitate ...

2011-12-1  flotation. FLOTATION PROCESS Flotation is a method of separating an ore species froth another, based on its hydrophobic surface characteristics either natural or induced when present as a suspension in water with air bubble. Due to the affinity of the desired mineral to adhere to air bubbles it is floated out of the ore slurry.

In cases where the ore does not contain carbonate minerals, direct pyrochlore flotation is applied using cationic amine collectors at acidic pH. A typical example is the flotation process applied at Araxa mine in Brazil [1].
