Dolomite

Dolomite is a vital calcium-magnesium resource primarily composed of magnesite and calcite, with minor amounts of clay minerals, chert, and occasionally gypsum, celestine, barite, pyrite, and organic matter. Boasting abundant reserves distributed across all provinces, proven dolomite deposits currently meet the demands of economic development. It serves as a high-quality raw material in industries such as metallurgy, chemical engineering, building materials, rubber manufacturing, and refractory materials.

Limestone

Limestone is a non-metallic mineral primarily composed of calcium carbonate (CaCO₃), with calcite and aragonite as main mineral components, and may contain impurities such as clay and dolomite. Physically, it appears as a white or grayish-white solid with a dense texture, but reacts vigorously with dilute acids to release carbon dioxide. Chemically, limestone decomposes into calcium oxide and carbon dioxide at high temperatures (approximately 825–1020℃), a property that forms the basis for quicklime production.

Marble

Marble is a common and versatile metamorphic rock primarily composed of calcium carbonate (typically accounting for over 50%), with minor amounts of magnesium carbonate, silicon dioxide, iron oxide, and other components. Additionally, it may contain minerals such as mica, bauxite, and garnet. It is mainly processed into various profiles and slabs for use as wall cladding, flooring, countertops, columns, and other architectural elements in buildings. It is also widely utilized as a material for monumental structures such as monuments, towers, and sculptures. Furthermore, its crushed stone and scrap materials can be used in the production of artificial stone, terrazzo, stone chips, and stone powder, or as fillers in industries including coatings, plastics, and rubber.

Limestone Rock

Limestone Rock is one of the most widely distributed and abundant sedimentary rocks on Earth, and also a core type of carbonate rock, playing a crucial role in geological evolution, industrial production, and ecological environments. Known as a "multi-functional industrial raw material," it boasts extensive applications across multiple fields and high utilization efficiency:

Construction and building materials sector; Industrial manufacturing sector: processed into stone powder for use as fillers in coatings, plastics, and rubber, or as whitening and thickening agents in papermaking and toothpaste production.
