Premium Pyrite (FeS2) Lumps for Industrial Applications

High-purity ferro sulfur lumps with guaranteed FeS2 content for consistent metallurgical performance. Ideal for steelmaking and iron production due to enhanced sulfur fixation and slag fluidity optimization.

Dense crystalline structure ensures slow-release sulfur properties, reducing oxidation during smelting. Manufactured through precision crushing/screening for uniform 10-50mm lump size with <5% powder content.

Key industrial uses:

- Essential deoxidizer in electric arc furnace steel production

- Cost-effective sulfur additive for cast iron foundries

- Fluxing agent for non-ferrous metal refining

- Raw material for sulfuric acid manufacturing

Bulk packaged in moisture-proof ton bags with reinforced lifting loops. Direct-from-mine pricing with volume discounts for industrial buyers. Meets ASTM E1070-17 standards for metallurgical-grade pyrite.

Ships globally with hazardous materials certification. Custom particle size distribution available for specialized applications.
