Dolomite

Dolomite (CAS 16389-88-1) is a naturally occurring calcium magnesium carbonate mineral used as a pH-adjusting and buffering agent.

Where is Dolomite used?

• Agriculture: raises pH and corrects magnesium deficiency in acidic soils, improving yields in magnesium-sensitive crops such as cereals and potatoes
• Water treatment: remineralizes soft or desalinated water, restoring alkalinity and hardness to drinking water standards
• Construction: filler and aggregate in asphalt, concrete, and road base materials
• Metallurgy: flux in steel and iron production to remove impurities during smelting
• Its dual calcium and magnesium content suits neutralization where soil or process chemistry demands both nutrients.

Good to know: Agricultural grades are commonly sold by mesh size; industrial grades may be specified by reactivity or neutralizing value.

Commercial specifications

• Particle size ranges from coarse agricultural lime to fine industrial powders
• Purity levels defined by CaCO3 and MgCO3 content
