Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.

Normally the flotation process is what is used to separate the graphite from the clay, if this is not happening you may need to adjust your reagents. Alternatively, if the clay is finely disseminated, classification will work after flotation. Do you have the quality specifications - physical (e.g., sizing) and chemical (impurities), etc.?

A novel and simple flotation technique has been developed to prepare high-purity graphite from impure graphite. In this method, a suspension of pristine powdered graphite (PG) is dispersed and stirred in water without adding froth formers or supportive chemicals. This makes fine particles of graphite move upwards and float on water.
