Raw Magnesite

Raw Magnesite (Magnesium Carbonate, MgCO₃) – Natural Mineral for Feed, Fertilizer & Industry

Product Overview

Raw Magnesite (MgCO₃), also known as Natural Magnesium Carbonate, is a high-purity mineral found in metamorphic and sedimentary rock formations. It serves as a primary raw material for producing magnesium oxide, magnesium sulfate, and other magnesium compounds. With its excellent alkaline properties, thermal stability, and high magnesium content, Raw Magnesite is widely used in animal feed, fertilizer, ceramics, refractories, and chemical industries.

At Tuna Sourcing, we supply ISO 22000-certified Raw Magnesite sourced from high-grade natural deposits. Our magnesite is carefully processed, screened, and graded to ensure uniform particle size, purity, and mineral consistency. Available in various physical forms (lump, granular, or powder), it meets international quality standards for feed, industrial, and agricultural applications.
