Key findings
What the evidence shows
World production and the largest producer
The USGS puts world production at 1,100 thousand metric tons. China is the largest producer with 88% of the total.
How concentrated supply is
The Herfindahl-Hirschman index over country shares is 7,736 (highly concentrated). The top three producers hold 95%; 1 country supplies half.

Supply structure: mine production by country
China is the largest producer of magnesium, at 87.7 percent of the published world total in 2025[1]. It is followed by Russia at 5.5 percent, Brazil at 1.8 percent and Israel at 1.8 percent. The USGS puts world production at 1,100 thousand metric tons; the sum of the country figures is 1,083 thousand metric tons, the difference being rounding in the published total.[1]

Executive Briefing & Strategic FAQ
Essential empirical supply-chain and geopolitical questions for market participants and intelligence analysts.
Which countries dominate global mining and refining for Magnesium?▼
Global Magnesium production is characterized by high geographical concentration in both raw extraction and chemical processing, as documented in MiningBridge's empirical supply-chain models.
What are the critical supply chain bottlenecks and geopolitical risks for Magnesium?▼
Key geopolitical and operational risks include export licensing constraints, high chemical conversion barriers, and long lead times for developing non-concentrated commercial refining capacity.
What are the primary commercial uses for Magnesium, and can it be substituted?▼
Magnesium is essential across energy transition, advanced electronics, and defense systems. While direct substitutes exist in select low-performance applications, replacing Magnesium in mission-critical hardware incurs significant metallurgical and cost trade-offs.
