Dolomite is a type of limestone, a type of sedimentary rock that contains a high percentage of the mineral dolomite. Calcium magnesium carbonate along with calcite and aragonite dolomite makes up approximately 2% of the earth’s crust. Dolomite crystals are colorless, white, buff-colored, pinkish, or bluish. Granular dolomite is a light to dark gray, tan, or white granular dolomite found in rocks. Dolomite crystals are translucent or nearly opaque, whereas dolomite grains in rocks are translucent or nearly opaque. Dolomite occurs widely as the major constituent of dolostone and dolomite marble. Dolomite-rich rocks in marine sequences originate from petrogenesis (formation of rocks, ingenious rocks). Dolomite is used to make refractory bricks because it contains magnesium metal and magnesia (MgO). Dolostone is often used for limestone in cement and bitumen mixes, as well as a flux in blast furnaces.

The global dolomite market is expected to surpass US$ 3.69 billion by the end of 2028 and exhibit a CAGR of 3.85% during the forecast period (2021 to 2028).


One of the key factors expected to stimulate market growth during the forecast period is multiple applications of dolomite in various industries. Dolomite is widely used in the building & construction industry. Aggregates made up of industry-waste dolomite are characterized by very high compression strength and resistance against abrasion and other mechanical impacts. Dolomite aggregates must meet a variety of criteria and requirements, depending on their intended application, to ensure the long life of building structures built on aggregate foundations and to assure their safe use.

Limestones and dolomite are also used as fluxes in smelting of metalliferous ores. They combine with impurities in the ores such as silica and alumina to form a fluid slag which can be separated from the metals. Dolomite is also used as a flux in the blast furnace for the production of pig iron from iron ore. Increasing demand for iron, especially in the construction sector, is expected to influence the global dolomite market growth.

Among regions, Asia Pacific held the dominant position in the global dolomite market in 2020, accounting for 40% market revenue share, followed by North America and Europe. According to a report by Multidisciplinary Digital Publishing Institute (MDPI) published in February 2021, mineral nutrients are essential for adequate growth, productivity, and health of all food-producing animals. Magnesium is considered one of the seven macro minerals that are essential in farm animal diets. Dolomite is the best source of magnesium and calcium used for animal feed, Dolomite is the best source of magnesium and calcium for animal feed, and the performance and efficacy of modern high-producing farm animals, as measured by feed conversion rate (FCR, kg feed per kg of animal product), has increased dramatically in recent decades, possibly contributing to changes in nutritional requirements of food-producing animals.

Market Restraints

High-grade phosphate reserves have begun to diminish worldwide, and consequently, low-grade phosphate rock is now explored as a potential fertilizer. Low-grade fertilizer is becoming popular in the agriculture sector because of its cost effectiveness and high availability, which is hampering the dolomite demand in the fertilizer industry. Another constraint to the dolomite market is that it must be activated during the fertiliser manufacturing process, which increases the amount of phosphorous and activates some heavy metals. Metals such as Cd, Cr, Cu, Pb, and Zn are active during the activation process. Impurities present in dolomite fertilizers such as lead (Pb) and arsenic cause several problems to humans after the consumption of arsenic- and lead-rich foods. Long-term exposure to arsenic from drinking-water and food can cause cancer and skin lesions. It has also been associated with cardiovascular disease and diabetes. Short-term exposure to lead causes vomiting, diarrhoea, headache, stomach ache, and fatigue. Long-term side effects could be learning disabilities, hyperactive disorder, and several neurological disorders. Such side effects could be the major restraints for the dolomite market.
