Calcite Powder, Color : White, Packaging Type : 50 Kg

Calcite Powder or Limestone is a common sedimentary rock composed primarily of the calcium carbonate mineral, calcite (CaCO3). Calcite Powder constitutes approximately 10 percent of the sedimentary rocks exposed on the earth's surface. Calcite Powder is formed either by direct crystallization from water (usually seawater) or by the accumulation of sea animal shells and shell fragments. In the direct crystallization case calcium ions in the seawater combine with atmospheric or dissolved carbon dioxide to form calcium carbonate, which is insoluble, precipitates out. Earth Minechem is into supplying, exporting and manufacturing Calcite Powder in India.Over time, layers of the calcium carbonate form, and with sufficient time and pressure from overlying materials, are transformed to solid rock. The chemical composition of seawater and its minerals contaminants will be recorded in the limestone impurities. Limestone frequently also contains the minerals dolomite or calcium magnesium carbonate (CaMg(CO3)2, and a second crystalline form of calcium carbonate, aragonite.
