Iron Sulfide (FeS2) – High-Purity Casting & Steelmaking Essential
Ultra-pure pyrite (FeS2) with 90-95% iron sulfide content for precision metallurgical applications. Specially processed to minimize impurities (<5% silica/ash) ensuring optimal sulfur release in steelmaking. Granular form (3-10mm) enables even distribution as floor aggregate or foundry counterweight. Non-sparking properties enhance safety in explosive environments. Key uses: sulfur additive in ductile iron casting, ladle furnace deoxidizer, concrete density modifier for industrial flooring. Vacuum-sealed 25kg bags prevent oxidation during storage. Bulk discounts available – direct from mineral processors with ISO-certified batch testing. Ships globally with hazardous materials documentation.
