Brief Description: Its chemical formula is CaMg(CO3)2 and it belongs to the category Carbonate Minerals. Its colour is ashy-brown and it has rhombohedral crystals, while its lustre is vitreous to pearly. Crystal system: triangular. Its specific gravity is 2.85 and its hardness ranges from 3.5 to 4. It is tougher when affected by acid solutions in comparison to limestone and it harder resists karst corrosion. It constitutes the primary mineral component of the sedimentary and transformed rocks. Carbonate rocks (limestone, dolomites, travertines, marbles and chalk) have many applications in our days and are included among the 30 most important raw materials. Dolomite is mainly used in glass and ceramics production, agriculture (ground neutralizations, fertilizers and animal nutrition) and as colour filler.
