In its natural state, calcium carbonate occurs as chalk, limestone and marble. Mississippi Lime ground calcium carbonate is mined from one of the purest limestone deposits in the world with an average purity of % CaCO 3.. Both wet and dry grinding methods are commonly used in processing the limestone for industrial uses.
Calcium carbonate (CaCO 3), which occurs primarily in the form of the minerals calcite and aragonite, is one of the most prevalent compounds on carbonate is not only the main component of marble, limestone and dolomite, it is also found in bones and teeth as well as the exoskeleton of crustaceans, coral, muscles, snails and protozoa.
Many minerals contain calcium. Calcium minerals are very common and can be mined anywhere. It is chiefly obtained from limestone, dolomite and gypsum. Common calciumbearing minerals include anhydrite (calcium sulfate), gypsum (hydrated calcium sulfate), and aragonite or calcite (calcium carbonate).

Calcium Carbonate powder is processed through naturally occurring high purity calcite ores containing CaCO3 as major component. The selected raw material been washed, crushed, and then classified precisely to attain the products of exceptional consistent performed desirable quality available in a variety of grades.
Limestone is a group of calcite and rare argonite in the science of minerals and chemical name for its calcium carbonate and its chemical formula (ca ca3). The theory of calcium carbonate contains 56% of the calcium oxide (ca o) and 44% of the carbon dioxide (co2) It has a few impurities such as magnesium, aluminum, silica and iron.
Data for the annual production of calcium carbonate are not readily available. Approximately 1 billion tonnes of its two principal ores, limestone and dolomite, are mined annually in the US. Given the relative amounts of lime that is used in different countries, an estimate of worldwide mining of calcium carbonate is 15 billion tonnes a year.
Precipitated Calcium Carbonate Production. Precipitated calcium carbonate is produced using the most economic process existing today. Limestone is converted into calcium oxide and carbon dioxide by means of calcination at temperatures in excess of 900°C. To ensure a high level of purity, the calcination process is carried out using natural gas.
Omya is a leading global producer of industrial minerals – mainly fillers and pigments derived from calcium carbonate and dolomite and a worldwide distributor of specialty chemicals.
The process by which limestone (calcium carbonate) is converted to quicklime by heating, then to slaked lime by hydration, and naturally reverts to calcium carbonate by carbonation is called the lime cycle. The conditions and compounds present during each step of the lime cycle have a strong influence of the end product, thus the complex and varied physical nature of lime products.

Calcium carbonate is a chemical compound with the formula Ca CO 3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs.
Calcium carbonate, as it is used for industrial purposes, is extracted by mining or quarrying. Pure calcium carbonate can be produced from marble, or it can be prepared by passing carbon dioxide into a solution of calcium hydroxide. In the later case calcium carbonate is derived from the mixture, forming a grade of product called "precipitated ...
