MagIron Tests Confirm High-Grade Pellet Quality for U.S. Steelmaking

The test program utilized concentrate from MagIron’s 2025 pilot plant, yielding pellets that demonstrated significant structural integrity and metallurgical efficiency. Standardized assessments recorded a cold compressive strength of 730 lbf per pellet and a tumble index of 96.8%, metrics that suggest the product can maintain bed permeability and withstand the rigors of modern shaft-furnace operations. Beyond physical durability, the pellets showed a near-zero reduction disintegration index of 0.13%, a key indicator for stable furnace performance and reduced dust generation.

These technical milestones bolster MagIron’s broader strategy to address domestic supply gaps in the U.S. steel industry, particularly as electric arc furnace production continues to grow. Executive Chairman Julian Treger noted that the findings prove the versatility of the company's Minnesota-based resources. While the firm currently prioritizes a pig iron development strategy, these results provide a viable alternative for producing premium feedstock should market conditions demand it. The company is now moving toward a final investment decision, with plans to share these performance results with potential strategic partners.
