Calcium carbonate is a chemical compound, also known as limescale in its precipitated form, and can be a big problem for any water supply. The compound is commonly found in water that has passed through limestone rocks and strata that contain a high content of minerals.Rainwater has sufficiently low pH to drag calcium carbonate out of rocks and into the groundwater.
Calcium carbonateis beneficial as the active ingredient in agricultural lime, but is usually the principal cause of hard water which is typically an unwanted quality.
Under normal conditions, calciumcarbonate is insoluble 8211 which means that scale can build up in water pipes and infrastructure. On the other hand, in groundwater, calcium carbonate has undergone chemical alteration to be soluble, though it only remains dissolved as long as it is underground,.
Along with scaling of pipes and associated equipment, calcium carbonate is often the cause of premature failure of O-rings and box seals in drilling rigs and other mining equipment.
All mining operations require the use of water, a prominent example is heap-leach mining where water is used to dissolve minerals from ore.
Granulated and Micronized Calcium Carbonate grades with high whiteness and purity degrees, are widely used in the process of Construction Chemicals due to its relevant cost. Producing appropriate AFS granulated size ranges of products, AL DOHA for Mining enriches the formulations of construction chemicals manufacturers.

Limestone is a naturally occurring mineral high in calcium carbonate, or CaCO 3 . to extract pure calcium from calcium carbonate through a multi stage process.
Calcium carbonate is one of the most abundant minerals and is the main constituent of limestone. Most calcium carbonate occurs as limestone, however, heat and pressure can result in the metamorphic form, marble. Calcium carbonate is generally mined as limestone or marble depending on application. Its chemical impurities, size distribution and physical makeup dictate its end use.
Calcium carbonate is mined for use in the paper and paint industries as a filler and coating agent, and in plastics for extending polymers and reducing costs. It is used in the pharmaceutical and food industries as a calcium and dietary supplement, and is also used in adhesives and caulks, joint and latex carpet compounds, and flooring and roofing materials.
The production of high purity calcium carbonate requires flotation to remove contaminants such as iron, magnesium, and silica silicates. ArrMaz high-grade cationic collectors and flocculants have been developed for this particular purpose and are custom blended for customer-specific use at each plant. ArrMazs technical experts will work closely with you to custom-formulate a reagent suiteand flowsheet design for your specific calcium carbonate flotation process.
T he gold mining industry is one of the major users of Calcium Carbonate Milk of calcium carbonate is used in the disposal technology of the acid mine drainage of gold neutralization in a high-density sludge and this is a relatively cheaper way to reduce treatment cost significantly.
Practically insoluble in water. Occurs extensive in rocks world-wide. Ground calcium carbonate CAS 1317-65-3 results directly from the mining of limestone. The extraction process keeps the carbonate very close to its original state of purity and delivers a finely ground product either in dry or slurry form.
