Pyrite is widely used in various industrial applications due to its unique properties. In the manufacturing of sulfur dioxide, it serves as a key raw material, which is essential for producing sulfuric acid, a critical component in chemical manufacturing, fertilizers, and petroleum refining. Additionally, pyrite is utilized in the production of iron sulfate, used in water treatment processes to remove impurities and as a soil amendment in agriculture. Its metallic luster and brassy color make it a popular choice in jewelry and decorative items, often marketed as "fool's gold." In the construction industry, pyrite is sometimes incorporated into concrete and other building materials for its density and durability. However, its presence in construction aggregates must be carefully managed to avoid potential issues with expansion and degradation over time. Pyrite also plays a role in environmental applications, such as in the remediation of heavy metal-contaminated water, where it helps in the adsorption and removal of pollutants.
