Dolomite

Dolomite (CAS 16389-88-1 ), a naturally occurring calcium magnesium carbonate mineral, is used across industrial and agricultural sectors primarily as a pH-adjusting and buffering agent. Its dual calcium and magnesium content makes it a preferred choice over single-element neutralizers where soil or process chemistry demands both nutrients simultaneously. In agriculture, dolomite is applied to acidic soils to raise pH and correct magnesium deficiency, directly improving crop yields in magnesium-sensitive crops such as cereals and potatoes. Water treatment facilities use it to remineralize soft or desalinated water, restoring alkalinity and hardness to meet drinking water standards for municipal and industrial use. In construction, it serves as a filler and aggregate in asphalt, concrete, and road base materials, where consistent particle size and carbonate content are critical to specification compliance. Metallurgical operations use dolomite as a flux in steel and iron production to remove impurities during smelting. It is supplied as crushed stone, ground powder, and micronized grades. Particle size ranges vary from coarse agricultural lime to fine industrial powders. Food-grade and technical-grade specifications are available, with purity levels defined by CaCO3 and MgCO3 content. Agricultural grades are commonly sold by mesh size, while industrial grades may be specified by reactivity or neutralizing value to ensure performance in chemical processes.
