roduct Overview

Pyrite (FeS₂) is a natural mineral raw material with high practical value in papermaking and dyeing industries, mainly used as papermaking cooking agent and sulfur dye raw material. It is processed by professional crushing and screening, with uniform 80–200 mesh particle size and sulfur content ≥35%, ensuring stable reaction performance. It is an ideal raw material for producing sodium sulfide, applying sulfate pulping and manufacturing dye intermediates, with excellent cost performance and wide industrial adaptability.
