MARKET INSIGHTS
Global Magnesium Raw Materials (Magnesite) Market size was valued at USD 2.14 billion in 2024. The market is projected to grow from USD 2.31 billion in 2025 to USD 3.68 billion by 2034, exhibiting a CAGR of 6.8% during the forecast period.
Magnesite, a magnesium carbonate mineral (MgCO₃), serves as the primary raw material for producing various magnesium compounds and refractory products. It exists in two main crystalline forms: phanerocrystalline (coarse‑grained) for refractory applications and cryptocrystalline (fine‑grained) used in chemical processing. The mineral undergoes calcination to produce dead‑burned magnesia (DBM), caustic‑calcined magnesia (CCM), and fused magnesia – essential materials for steelmaking, construction, and environmental applications.
Market growth stems from increasing steel production requiring refractory materials, coupled with rising demand for magnesium compounds in wastewater treatment and agriculture. However, China’s dominance in production (controlling over 70% of global magnesite reserves) creates supply chain vulnerabilities. Recent developments include RHI Magnesita’s 2024 expansion of its Brazilian magnesite mine to reduce dependency on Chinese imports, reflecting industry efforts to diversify supply sources amid geopolitical tensions.
