The calcium carbonate is a sedimentary rock which is mainly composed of calcite mineral (calcium carbonate: CaCo). The calcium carbonate is often composed of various quantities of silica mineral in the form of chert or flint, as well as various amounts of clay, silt, and sand, as intercalations, nodules or interbedded layers. The main source of calcite in limestone is usually marine organisms, so that their shells deposit on the ocean floor. As well, the secondary calcite may be deposited by supersaturated meteoric waters (ground waters that cause the deposition in caves), and consequently cave deposited layers such as stalagmite and stalactite are formed.

Tanin Arad Yekta Company started its commercial activity in to supply raw materials for paints, plastics, inks, and adhesives industries, and since it has participated in and produced micronized mineral powders of calcium carbonate, talc, barite, ocher, lithopene, etc. It has micronized very soft granules in Aligudarz city. This company, by using experienced and experienced staff in the field of preparation and supply of various materials and providing technical advice, regarding the optimization of formulations and reducing the cost in the paint industry and other related industries, is an effective step for the country&#;s industries to flourish.

Pure limestone is often found in white and whitish colors. Due to the presence of impurities such as clay, organisms remains, iron oxide and other components, most of the limestone are found in different colors, especially if they are weathered. Based on their formation process, limestone could be seen in crystalline, clastic, granular or massive forms in nature. The presence of calcite, quartz, dolomite or barite crystals may create some small cavities in rocks. The Folk and Dunham classifications are used to scrutinize the limestone in detail.

ساختار اندام دام دارای ذخایری از منیزیم است. که بخش عمده ای از آن در است.خوان های مهره ها و دنده نگهداری می شود. و هنگامی که در دام ها کمبود منیزیم اتفاق می افتد،به منظور جبران آن از ذخیره منیزیم است.خوان‌هایشان است.فاده می‌کنند. که این حالت در دام های جوان اتفاق می افتد  در حالی که دام های بالغ به علت کمبود منیزیم در اثر بروز Tetany تلف می شوند.
