GCC

Brief introduction of GCC

Ground Calcium Carbonate is processed through naturally occurring high purity Limestone/Dolomite/Marble/calcite ores containing CaCO3 as major component. The selected raw material has to be washed, crushed ,fine grinded and then classified precisely to attain the products of exceptional consistent & desirable quality available in a variety of grades.

Main Applications of GCC

Application Fields		Main Purposes
Metallurgy		In steelmaking and ironmaking, limestone acts as the carrier of calcium oxide and can combine unnecessary or harmful accompanying elements such as ash in coke, silicon, aluminum , sulfur, phosphorus and turn into fusible slag out of the furnace.
Chemical		Rubber, calcium carbide, bleaching agent, alkali, soda, calcium nitrate, calcium chloride, calcium sulphate, calcium phosphate, nitrogenous, carbon dioxide, calcium oxide, precipitated calcium carbonate, etc.
Construction		Ingredients of mortar, all kinds of lime, aggregate, pitch, etc.
Agriculture and Forestry		Calcium fertilizer, acidic soil amendment, feed , epidemic prevention, pesticide, disinfector
Building Materials	Cement	Portland cement
	Glass	Raw material of calcium oxide as the stabilizer in glass
	Ceramic	Raw material of calcium oxide
Food		Sugar manufacturing、food storage（preservative）, etc
Environmental Protection		Flue gas desulfurization、industrial waste water treatment, etc
Others		Tanning、printing and dyeing、nonferrous metal,etc
