Dolomite lumps

Specifications Particular: - Glass Grade Dolomite (brightness 90%94) Mesh Size: - 20-80 Mesh Al2O3 0.512 % MgO 22.533 % CaO 29.534 % Fe2O3 0.181 % Sio2 4.287 % Applications Dolomite is used for a variety of purposes as it is a versatile rock. It is mainly used in the construction industry and is often used as a substitute for limestone. Industrial uses of dolomite include the manufacturing of glass (the glass manufacturing industry uses pre-calcined dolomite, which theoretically contains about 21.8% magnesium oxide, or MgO). It is used in certain industries, such as the iron and steel-making industries, as a refractory and also as a flux. Dolomite is burnt, hardened and then made into small pellets and heated again. These pellets of dolomite are then used in the manufacture of blocks of dolomite refractory. Calcined dolomite with added iron oxide is used to repair the inner linings of furnaces. It is crushed into a fine powder called aglime, which is used for agricultural purposes (it reduces the acidity of the soil), and in the filler-making industry.
