Magnesium Oxide Powder All Costs
Magnesium Oxide Cost: Raw Material
Magnesium oxide powder is primarily derived from magnesite, a mineral rich in magnesium carbonate. The quality and purity of magnesite significantly affect the production cost of MgO powder.
Global Distribution of Magnesite (2023)
| Region | Share of Global Reserves (%) | Average Purity (% MgO) | Characteristics | Production Areas |
|---|---|---|---|---|
| China | 60 | 46–48 | Largest reserves, high-purity deposits | Liaoning, Shandong |
| Turkey | 15 | 43–45 | Known for moderate purity | Eskisehir, Kutahya |
| Russia | 10 | 42-44 | Contributes mainly to Eastern Europe | Ural Mountains, Siberia |
| Others | 15 | 40-42 | Smaller reserves, varying quality | Brazil, North Korea, Greece |
Where is CHIMAG Factory?
Located in Yingkou, Lioning, China, the original of the highest-purity magnesite.
Purity Levels of Magnesite
1. High-Purity Magnesite (46%–48% MgO Content)
High purity magnesite is the most sought after material due to its superior quality and performance characteristics. It is characterized by good thermal stability, chemical reactivity and reliable performance under stringent conditions. High-purity magnesium oxide powder content ensures minimal impurities, making it ideal for industries requiring precision and high standards. It is mainly found in Liaoning Province, China.
Applications
- Technical-Grade Magnesium Oxide: Production of high-performance rubber, ceramics, and water treatment chemicals.
- Pharmaceutical-Grade Magnesium Oxide: Antacids, laxatives, and dietary supplements.
- High-Temperature Refractory Materials: Applications in kilns and furnaces.
2.Lower-purity magnesite (<40% MgO content)
Low purity magnesite contains higher levels of impurities such as silica, iron and calcium, making it suitable for less demanding applications. Although it has limited use in high-precision industries, it is valuable in batch industrial applications. Although it has higher levels of impurities compared to high purity magnesite, it can provide moderate thermal stability and adequate reactivity for industrial processes. It is mainly found in Turkey, Russia and other areas with low MgO concentrations in magnesite reserves.
Applications
- Industrial-Grade Magnesium Oxide: Steel manufacturing as a desulfurizer.
- Construction Materials: Fire-resistant boards, cement additives, and insulation materials.
- Agricultural Additives: Fertilizers and soil conditioners, aiding in pH adjustment and nutrient supply.

Magnesium Oxide Cost: Production Process
Magnesium oxide production starts with mining and crushing raw magnesite into smaller pieces for calcination. The material is then heated in kilns or reactors at 800°C–1,200°C, converting magnesium carbonate to magnesium oxide. After calcination, it is ground into fine powder using pulverizers and graded for particle size. Samples undergo purity and reactivity testing before being packaged in moisture-proof bags to prevent contamination.
Machinery Costs
| Equipment | Function | Cost Range (USD) |
|---|---|---|
| Rotary Kilns | Calcination | $500,000–$1,000,000 |
| Milling Machines | Grinding calcined MgO | $50,000–$200,000 |
| Grading Equipment | Ensures particle uniformity | $20,000–$50,000 |
Labor Costs
Average manufacturing wages in China: $500–$700 per worker/month. Labor costs are significantly lower than in Western countries, providing cost advantages for Chinese suppliers.
Transportation and Logistics
| Aspect | Details |
|---|---|
| Sea Freight Cost | $50–$100 per metric ton |
| Shipping Time | 20–25 days by sea |
| Additional Costs | Customs duties, port fees |
