DOLOMITE
INTRODUCTION
Dolomite's applications span the construction materials industry, ceramics, glass and refractory products, chemical manufacturing, agriculture, environmental conservation, and energy-saving technologies. It is predominantly used as a base material for blast furnace refractories and as a flux in the ironmaking process.
Furthermore, it plays a significant role in the production of calcium magnesium phosphate fertilizers and the preparation of magnesium sulfate, as well as being a vital ingredient in glass and ceramic production. China's dolomite reserves are plentiful, with confirmed reserves adequate for the needs of economic construction. Most of these reserves have been tapped into, with production occurring in various provinces, especially in Kazuo County, Chaoyang City.
Our dolomite products, sourced from the high-quality mineral area of Liaoning Province, contain a low iron content that meets the exceptional standards required by the glass industry.

APPLICATION
- Widely used in industrial field
i. Building materials
Dolomite plays a key role in the building materials industry. After calcination at high temperature, it will produce magnesium oxide and calcium oxide, which are often used in the production of refractory materials, glass and ceramics because of their high stability and excellent high temperature resistance. In the lining of metallurgical furnace, dolomite can resist high temperature erosion, effectively prolong the service life of furnace lining, and ensure production safety; In the field of architectural coatings, its characteristics help to improve the quality and performance of coatings.
ii. Glass and ceramic manufacturing
In the glass manufacturing process, the magnesium element in dolomite can significantly improve the chemical stability and mechanical strength of the glass, making the glass more durable. And in the ceramic industry, dolomite can reduce the firing temperature, not only save energy costs, but also improve the glaze gloss, so that ceramic products more beautiful and quality sense.
- Assistance in agriculture
i. Soil amendments
Dolomite powder is the kryptonite of acidic soil, which can neutralize soil acidity and accurately regulate pH. At the same time, it can supplement the soil with magnesium, calcium and other key nutrient elements, which are like the "nutrient meal" of the soil, helping to promote the growth and development of crop roots, enhance the efficiency of nutrient absorption of crops, and thus significantly improve crop yield.
ii. Fertilizer additives
Dolomite can be used as an important component of slow-release fertilizer to release magnesium slowly and continuously, avoid soil compaction and continuously optimize soil structure. This feature enables crops to obtain nutrients steadily throughout the growth cycle, ensuring their healthy and vigorous growth.
- Contributions to the field of environmental protection
i. Water purification
Dolomite, with its unique porous structure, shows strong adsorption capacity and can effectively adsorb heavy metal ions in wastewater, such as lead and cadmium, greatly reducing the risk of water pollution. At the same time, its alkaline component can neutralize acidic wastewater, effectively reduce environmental pollution, and help water purification and ecological restoration.
ii. Waste gas treatment
In the field of industrial waste gas desulfurization, dolomite as an adsorbent can efficiently absorb sulfur dioxide and other harmful gases. It is like a defense line of environmental protection, effectively reduce the content of harmful substances in exhaust emissions, reduce pollution to the atmospheric environment, and provide strong support for the realization of green production.
