Beneficiation Process of Kaolinite Clay: Kaolin Processing
The tailings from this final flotation step represents the beneficiated kaolin and is pumped to a thickener. Sulphurous acid is added to the pump to produce a pH of 2.8 to 3.0 for flocculation. The froth products from the reflotation and scavenging steps are combined and impounded.
