Flotation, nke a makwaara dị ka froth flotation ma ọ bụ ịnweta flotation, bụ usoro ịba uru nke na-ekewa mineral bara uru na mineral gangue na gas-mmiri siri ike interface site na iji ọdịiche dị na ọdịdị elu nke mineral dị iche iche dị na ore. A na-akpọkwa ya “nkewa nke ihu.” Ọ bụla usoro na ozugbo ma ọ bụ udiozi utilizes interfacial Njirimara nweta urughuru nkewa dabere na iche na elu e ji mara nke ịnweta ahụ a na-akpọ flotation.
