In the share of filler and pigment use in the production of paper, calcium carbonate amounts to 32%. It follows Kaolin (white clay) with 42%, and it is followed by sedimentary calcium carbonate with 12% and talc with 9%. Products of company White Rock that can be used in the production of paper:
Calcium carbonate, or CaCO3, comprises more than 4% of the earth's crust and is found throughout the world. Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years.
Maria D.S. Barroso, in Toxicology in Antiquity (Second Edition), 2019. 28.5 Pearls and Modern Chemistry. Calcium carbonate is a known antacid. It is the primary structural mineral in the body. It helps to regulate cell permeability, maintains acid–base balance, is involved in nerve transmission and muscle relaxation, and is required for phosphorus metabolism and energy production in the
Calcium carbonate fillers may also contain some related magnesium containing minerals such as magnesite (MgCO 3) and dolomite (CaCO 3 ·MgCO 3). Commercially viable deposits of calcite occur throughout the world, but differ considerably in purity and origin. The main sources of calcium carbonate fillers are chalk, limestone, and marble.

CaCO3) is a nontoxic and odorless inorganic salt, commonly found as a white mineral (calcite) which occurs naturally in chalks, limestones and marbles.
Calcite ( Calcium Carbonate – CaCO3 ) has a defining Mohs hardness of 3, specific gravity of 2.71 and its luster is vitreous in cyrstallized varieties. Color is white or none, though shades of gray, red, orange, yellow, green, blue, violet, brown or even black can occur when the mineral is charged with impurities.
Precipitated calcium carbonate, made by dropping calcium oxide into water, is used by itself or with additives as a white paint, known as whitewashing. Calcium carbonate is added to a wide range of trade and do it yourself adhesives, sealants, and decorating fillers. Ceramic tile adhesives typically contain 70 to 80% limestone.

Introduction Precipitated calcium carbonate (PCC) is a filler used in many appliions, like papers, plastics, rubbers, paints, drugs and so on. Its high purity, wellordered particle size and morphology makes it the white filler of choice.1 In paint
20191115&ensp·&enspData 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.
