Dolomite

Dolomite (Calcium Magnesium Carbonate, CaMg(CO₃)₂) – Dual Calcium & Magnesium Source

Product Overview

Dolomite (CaMg(CO₃)₂) is a natural mineral composed of calcium carbonate and magnesium carbonate, offering a balanced source of both essential elements. With its stable crystalline structure, high purity, and excellent neutralizing capacity, Dolomite is widely used in animal feed, fertilizers, soil conditioning, glass, ceramics, and steel industries. It plays a critical role in balancing pH, enriching nutrient profiles, and supporting healthy growth in both plants and livestock.

At Tuna Sourcing, we supply ISO 22000-certified Dolomite extracted from high-grade mineral deposits and processed into calibrated granular, powdered, or micronized forms. Each batch is tested for purity, fineness, and heavy metal safety, ensuring it meets international feed and industrial standards. Our Dolomite is suitable for feed-grade mineral premixes, agricultural soil improvement, and technical manufacturing processes.
