Calcium carbonate

Calcium carbonate

Calcium carbonate, a chemical compound with the formula CaCO3, is a common substance found in rocks as the minerals calcite and aragonite. It is the main component of shells of marine organisms, snails, pearls, and eggshells. Calcium carbonate is a versatile material used in numerous industries and has several practical applications.

Origins

Calcium carbonate is one of the most abundant minerals on Earth, accounting for about 4% of the Earth’s crust. It occurs naturally in three principal rock types: chalk, limestone, and marble. Each type forms through unique geological processes, making calcium carbonate a prevalent and varied mineral. If you want to learn more, please visit our website Calcium Carbonate wholesale.

Ground Calcium Carbonate (GCC) – created by nature over millions of years

Most calcium carbonate deposits originate from the remains of marine organisms that settle to the bottom of shallow seas. Organisms such as crustaceans, algae, and coral absorb calcium carbonate from the water to form their skeletons and shells. Once they die, their remains accumulate to form sedimentary deposits on sea beds, eventually transforming into rock.

Chalk is a soft rock resulting from poorly compacted sedimentary calcium carbonate, whose diagenesis is incomplete. The formation of limestone follows once the sedimentation process is complete.

Marble, the hardest form of calcium carbonate, is a metamorphic rock formed through the recrystallization of limestone under high pressure and temperature conditions.

Precipitated Calcium Carbonate (PCC) – created by man in a matter of hours

Calcium carbonate can also be synthetically produced as Precipitated Calcium Carbonate (PCC). PCC is generated by converting limestone into CaO and CO2, followed by the reaction of these purified components in a chemical reactor. While PCC has the same chemical formula as GCC, it exhibits different properties, such as higher purity, varied particle size distribution, and particle shape.

The high whiteness and opacity of calcium carbonate make it suitable for various applications, from building materials to paper, paint, construction, and foodstuffs.

Calcium Carbonate Market Size, Trends, Growth & Forecast

Market Overview

In H1 2024, leading producers of calcium carbonate included Minerals Technologies Inc., United States Lime & Minerals, Inc., and Omya. By April 2024, Minerals Technologies Inc. had entered long-term agreements to establish and operate on-site PCC satellite plants with Andhra Paper Limited in India, Nine Dragons Paper in China, and Zhejiang Zhefeng New Materials Company in China. These plants, with a combined production capacity of over 180 thousand tonnes of PCC, are expected to become operational between late 2024 and early 2024.

Asia Pacific was the foremost consumer of calcium carbonate in H1 2024. Market prices in China showed mixed sentiments, with a notable price rise in early 2024 due to labor shortages during the spring festival, followed by a price decline as production resumed. The US market experienced volatility, with significant price fluctuations in response to inflation, market demand, and financial crises.

The global calcium carbonate market reached approximately 9 million tonnes in 2022 and is anticipated to grow at a CAGR of 4.53% until 2035.

Industry Applications

Calcium carbonate is crucial for the construction sector, used in cement manufacturing and as a standalone building material. It is used in mortar, roofing tiles, concrete slabs, and more. Calcium carbonate also serves as a filler in paints and pigments, enhancing the brightness and smoothness of paper sheets used in various industries like packaging and tissue papers. Other applications include baking powder, wine, dough, plastics, adhesives, and sealants.

Paper and Pulp Industry

The demand for calcium carbonate is driven primarily by the Paper and Pulp industry due to its paper-brightening, light-scattering, and ink-retaining properties. Approximately 53% of the calcium carbonate market was consumed by this industry in 2022, where it is used as a filler and coating pigment to improve brightness and opacity.

Geographical Demand

The Asia Pacific region demands the most significant volume of calcium carbonate due to ongoing infrastructure development and rising needs in the paints, coatings, and automotive sectors. Belgium leads in global exports of calcium carbonate, supplying it for various industrial applications worldwide.
