Limestone is natural ore raw material mainly composed of calcium carbonate with hard texture and abundant reserves. It is the most basic upstream raw material for cement, glass, metallurgy and building materials industries, which can be used directly after crushing or calcined into quicklime and hydrated lime products.
| Chemical Name | Calcium Carbonate |
| Chemical Formula | CaCO₃ |
| CAS No. | 471-34-1 |
| Appearance | Bluish gray and grayish white natural ore stone |
| Melting Point | 825℃ (decompose at high temperature) |
| Density(20℃) | 2.70g/cm³ |
| Solubility | Hardly soluble in water, soluble in strong acid to release carbon dioxide |
| Stability | Extremely stable at normal temperature and pressure, weather resistant, easy to decompose into quicklime and carbon dioxide at high temperature |
Used as core stone material for cement production, flux raw material for glass firing, blast furnace smelting flux, raw stone material for light and heavy calcium carbonate, road base crushed stone aggregate, circulating water filter material and building stone processing raw material.
Stack separately in open stockyard classified by particle size, no strict moisture-proof required, avoid mixing with soil impurities, keep away from dusty light materials for convenient loading, unloading and crushing processing.
