Special Applications of High‑iron Pyrite powder
High‑grade massive pyrite ore is distinguished from ordinary pyrite by its high sulfur and iron content, controllable impurities, and dense structure, giving it high‑end industrial value. It is mainly applied in five major fields: high‑end metallurgy, new energy materials, functional materials, precious metal recovery, and environmental protection.
High‑End Metallurgical Sulfur Addition and Furnace Charge
As a controllable high‑purity sulfur source, it is used in the smelting of special steels such as free‑cutting steel, 303 stainless steel, and H13 die steel. It precisely controls the sulfur content in steel within 0.06%–0.30%, significantly improving the machinability, surface finish, and tool life of steel products.
It also serves as a furnace charge auxiliary for precision casting and special steel smelting, enhancing melt fluidity and slag‑forming performance to improve the quality of castings and steel products.
Core Raw Materials for New Energy
It is used to extract 6N‑grade high‑purity sulfur for sulfide solid‑state battery electrolytes, serving as a critical sulfur source for next‑generation high‑energy‑density and high‑safety solid‑state batteries. It can also be used to produce battery‑grade sulfuric acid and iron‑based precursors, supporting the industrial chain of lithium‑ion and sodium‑ion batteries.
Special Applications in Functional Materials
As a functional filler for friction materials such as resin grinding wheels and brake pads, it adjusts friction coefficients and improves wear resistance and stability.
As a coloring raw material for brown glass, it precisely controls glass color and light transmittance through iron ions.
Key Raw Material for Precious Metal Roasting
In the roasting process for recovering precious metals including gold, silver, platinum‑group metals, and copper, it acts as a combustion improver, carrier, and collector simultaneously, increasing precious metal recovery rates and smelting efficiency.
Environmental Protection and Comprehensive Resource Utilization
It is used as a flue‑gas desulfurizer and heavy‑metal ion adsorbent for industrial wastewater and waste‑gas treatment.
Yunfu Pyrite Mine boasts large ore reserves and output, high grade, low impurities, stable quality and guaranteed delivery time.
