The iron sulfide manufacturer tells you what the sulfur content of pyrite is generally

Pyrite is a natural mineral, which is obtained by mining. It is a basic chemical raw material. Its direct application is to produce sulfuric acid, and most of the sulfuric acid is used to produce chemical fertilizer.

This mineral is generally called pyrite, pyrite or pyrite in Chinese. Due to the corresponding HS code during customs declaration, it is also called unfired pyrite (but this name is rarely used in daily work). The molecular formula FeS2 is translated into pyrite or iron pyrites in English, and sometimes into ferro sulfide, so it is sometimes also called iron sulfide or iron sulfide in Chinese.

But in Chinese, pyrite and iron sulfide are different products. It is a kind of primary ore, with molecular formula FeS2 and HS code of 25020000. Iron sulfide is prepared by the reaction of iron pin and sulfur powder, with molecular formula FES and HS code of 2830909000.

The higher theoretical sulfur content of pyrite is 53.45%, and the higher theoretical iron content is 46.55%, but the general sulfur content is about 35%. Natural products often contain silicon, lead, zinc, copper, arsenic, carbon and other elements. The color is mostly light brass or gray black. The surface is metallic luster, and the powder is usually gray black.

After processing, picking out miscellaneous stones, drying, crushing, screening and other processes, ordinary pyrite will increase the sulfur grade to about 48%. It is also used in smelting and casting sulfur additives, abrasives, lithium batteries, environmental protection, counterweight and other industries.
