Clay quarry

Clay is Hydrous Al Silicate.► •We have two quarries of clay► Clay 1 (rich with Alumina –dark in color )► Clay2 (rich with Silica –lighter in color )► Clay is the source of (Al-oxides & Si-oxides

inlarge amount and Fe-oxides in small amount )

Stages of clay quarry► 1) Removing the over burden layer► 2) Ripping (because it is softer than L.s).► 3) Transporting .
