Limestone is widely used in chemical products and construction materials. powder and lumps .
Vietnamese Limestone Powder is one of the most popular materials for producing animal feed worldwide. It is rich in calcium content and low in metal, which makes big contribution to the development of animals. Application: Manufacturing Feed Additives For Fish, Shrimp, Layers, Broilers, Swine, Cattle. Materials: High quality Limestone, Calcium (Ca) > 38%, Ferrous (Fe2O3) < 0.05%, Magnesium Oxide (MgO) b< 0.2%, Whiteness: 90%, Brightness: 85%, Moisture: < 0.15%.
Dolomite is a carbonate mineral, including ankerite and manganese dolomite. Its crystal structure is like calcite and is often rhombohedral. It will bubble slowly when exposed to cold dilute hydrochloric acid. Some dolomite emits orange light under cathode ray irradiation.
Dolomite is the main mineral composition of dolomite and dolomitic limestone. Dolomite can be used in building materials, ceramics, glass and refractory materials, chemical industry, agriculture, environmental protection, energy conservation and other fields. It is mainly used as flux for basic refractory and blast furnace ironmaking. Production of calcium magnesium phosphate fertilizer and preparation of magnesium sulfate; As well as ingredients for producing glass and ceramics.
LIMESTONE (calcium carbonate) is characterized by high purity (99.23% CaCO3) and high whiteness 96.1%
We can supply LIMESTONE in powder form, as per the required micron size, from 45 micron up to 500 micron and by any quantities, packages and sizes

Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris.
CaCO3 - 80.2%
MgCO3 - 4.9%
SiO2 - 14.5%
