Dolomite Price and Production Outlook
Global dolomite production in 2025 is estimated 191 to 195 million tonnes, reflecting its role as a high-volume, low-cost industrial mineral used across construction, steelmaking, glass, agriculture and environmental applications. Supply growth is driven by infrastructure development, steel and cement demand, water treatment needs and soil conditioning requirements.
Industry conditions balance abundant geological availability with local quarry permitting, transport costs and energy intensity of calcination. Prices remain regionally determined, shaped by distance to end users, product grade (raw vs calcined), and processing intensity. The global picture shows steady capacity growth aligned with construction cycles rather than rapid expansion.
Production leadership is concentrated in regions with accessible carbonate deposits and proximity to industrial demand, including Asia Pacific, Europe and North America. Many markets remain locally supplied, with limited long-distance trade due to bulk density and logistics economics.
Buyers value consistent chemistry, controlled particle size, reliable supply and regulatory compliance.
