Limestone is a naturally formed biogenic sedimentary rock mainly composed of calcium carbonate. Formed through millions of years of biological accumulation and chemical precipitation, it continuously evolves to form unique karst cave landforms under water dissolution. With simple processing procedures including crushing, grinding, and calcination, limestone can be converted into high-value products widely used in construction, industry, environmental protection, and agriculture. Understanding limestone’s basic attributes and processing characteristics is the foundation for efficient and economical utilization of this essential mineral resource.
