Natural Flake Graphite | Asbury Carbons
The graphite/ore-rock slurry is then fed to froth floatation cells. Froth floatation is a method of beneficiation which relies on the differences between the surface chemistry of the country rock and the mineral being extracted, in this case graphite flake. In the cell the ore is mixed with water and "floatation agents".

Flotation | Centre for Minerals Research - University of Cape Town
Flotation. Background. Froth flotation is the follow-on operation, after comminution and classification, in the process of liberating and separating minerals by exploiting the differences in physical properties of the different minerals that make up an ore. Froth flotation is achieved when particles are separated based on their surface potential.

This method of froth floatation is a method of mineral processing in which different minerals are separated selectively. Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted by using froth floatation. The minerals that do not float into the froth are called the flotation tailings or flotation tails.

What is Electrocoagulation (EC)? | WaterTectonics
As water passes through the electrocoagulation cell, multiple reactions take place simultaneously. First, a metal ion is driven into the water. On the surface of the cathode, water is hydrolyzed into hydrogen gas and hydroxyl groups. Meanwhile, electrons flow freely to destabilize surface charges on suspended solids and emulsified oils.
