Dolomite industrial waste is generated mainly due to the crushing and processing of dolomite stone during mining and production activities Chemical properties Dolomite CaMg CO 3 2 a rock forming mineral is primarily composed of calcium oxide silica magnesium oxide and small amounts of aluminum oxide and iron oxide The main elements in
Mine head stocks of dolomite at the end of the year 2013 14 was 2 509 thousand tonnes as against 2 269 thousand tonnes in the previous year Table 7 The average daily employment of labour in 2013 14 was 3 412 as against 3 986 in the previous year The prices of dolomite are furnished in General Review on Prices 16 3
Dolomite is a sedimentary rock that primarily consists of calcium magnesium carbonate CaMg CO3 2 It is formed through the alteration of limestone or lime mud by magnesium rich groundwater Dolomite is often found in extensive beds and its color can range from white to gray to pink depending on impurities present in the rock
This is indicative that dolomite V has formed The dolomite V exhibits an ordered crystal structure in which twisted cationic polyhedron CaO 8 and MgO 6 square antiprisms and tilted CO 3 groups are alternately arranged along the a axis Fig 5 B Dolomite V still exists after temperature quenching and the pressure is decreased from 40 to 13 GPa
