Pyrite-types Of Ores
Product Overview
Industrial-grade Pyrite (FeS2) is a dense, high-sulfur iron sulfide mineral utilized as a primary or supplementary sulfur-bearing raw material across multiple high-temperature and chemical processes. Depending on industrial requirements, we supply pyrite in lump, granular, and micronized powder forms tailored for sulfuric acid manufacturing, metallurgical alloying, friction material compounding, and inorganic chemical synthesis.
Product selection is governed by end-process operational parameters, including active sulfur yield, iron ratio, heavy metal impurity limits, particle size distribution, and surface moisture levels. Each commercial batch is processed to meet strict industrial thresholds and is verified through laboratory testing prior to dispatch.
High Sulfur & Iron Yield: Consistent mineral composition designed to optimize sulfur dioxide (SO2) generation rates in roaster furnaces and provide reliable iron-sulfur contribution in metallurgical applications.
Application-Specific Sizing: Comprehensive mechanical processing lines deliver exact particle size distribution—from coarse aggregates (0-30mm) to ultra-fine powders (325 mesh)—matching specific feeding equipment requirements.
Rigorous Impurity Control: Strict monitoring of trace elements such as arsenic (As), lead (Pb), and zinc (Zn) to prevent downstream catalyst poisoning and environmental compliance issues.
Low Moisture & Anti-Caking Protocols: Dry indoor storage and beneficiation maintain surface moisture below strict commercial thresholds, preventing bridging or caking during long-distance maritime transit.
Full Batch Traceability: Every shipment is tied to extraction shift logs and internal laboratory testing records, ensuring consistent performance across multi-ton production cycles.
Applications
Sulfuric Acid and Chemical Production: Utilized as a stable sulfur feedstock in roaster furnaces for generating sulfur dioxide (SO2) gas, which feeds downstream sulfuric acid plants and iron oxide pigment synthesis lines. Suitability depends on active sulfur content, impurity ceilings, and roaster thermal dynamics.
Metallurgical Processing and Foundry Applications: Applied as an economical sulfur and iron additive in grey and ductile iron casting to regulate metallurgical structures, control micro-deficiencies, and improve overall metal machinability.
Friction Material Manufacturing: Incorporated as an active inorganic mineral filler in heavy-duty brake pads and clutch facings. It provides stable friction coefficients and anti-wear characteristics under high thermal stress conditions.
Research and Material Development: Developed as a reliable raw material precursor for laboratory synthesis and pilot-scale trials involving iron sulfide-based advanced energy storage and specialty chemical compounds.

Processing and Preparation
Our processing workflow incorporates raw ore sorting, multi-stage crushing, screening, grinding, and closed-circuit air classification. The exact routing is engineered to prevent excessive ultra-fines in coarse aggregate grades while maintaining strict top-cut limits for micronized powders.
Quality Inspection Protocol
Every production batch undergoes rigorous internal testing prior to packaging. Key inspection metrics include:
- Active sulfur and iron concentration ratios
- Trace heavy metal limits (Arsenic, Lead, Zinc)
- Surface moisture and particle size distribution (d50 / d90)
- Visual appearance and packaging integrity
Particle Size Customization: Milling and air-classification circuits can be configured to meet custom d50 targets or specialized mesh distributions.
Chemical Blending: Ore mixing capabilities to achieve precise S/Fe ratios required by specific chemical reactors or industrial furnaces.
