Where clay is formed from the weathering of silica rich rocks such as granite and gneiss, it occurs with feldspar and quartz. The clay is separated from the other constituents by washing with water cannons and the slurry is then centrifuged to remove 75% of the minus 0.002mm fraction.
Clay is also processed to remove any contaminating materials such as iron, aluminium quartz and feldspar. It is dried and fired to produce molochite and then fed into a ball mill. Various product gradations can be produced. Felspar powder processing operation involves drilling, crushing, grinding, screening, drying, separation and dust cleaning of the feldspar.
