It mainly contains hydrated magnesium silicates and is found in the shape of lenses or veins inside the rocky base, especially the base and upper-base veins। The dimensions of raw bodies amount to 80 m. high and 50 m. wide and range from 20 m. to 5 m. in thickness. The reserve of it is estimated to be 365 thousand tons.
Feldspar is used in various industries, but it is mainly used in thermal industries such as in the making of pottery, porcelain, faience, glass and metal painting through functioning enamel। A little amount of it, not more than 10 %, is used for other purposes like the filling materials, painting and for the making of some sorts of soap.
Dolomaite
Dolomite is calcium – magnesium carbonates, located in Egypt at Sadat area 30 km south Suez governorate and Ataqa area in Suez. There are 3 types of dolomite: industrial dolomite, construction dolomite and steal dolomite.
Sandstone is found in the shape of layers that range in thickness. It consists of adjacent granules distinguished for its various colors as including iron oxides. Sandstone is used in construction activities, coating Nile bridges, making millstones, whetting weapons and sometimes is used for décor.
