Flotation is used in gold, mineral processing, copper, coal, to recover fine particles, typically finer than 05 mm Chemical and physical attachment of the solid particle to the bubble, induced by the chemical reagents and conditioners would be a over simplified description of froth flotation
Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized
At this stage after a mineral ore that is refined inserted into the machine agitator tank which is usually also called a flotation cell to produce a pulp slurry concentrate In the process of this flotation Reagent Which In Use Is a form of lime , bubble and collectors
