Pyrrhotite is the most common and iron sulphide mineral in mine wastes worldwide.

磁黄铁矿是矿山尾矿堆中最为常见且分布很广的一种硫化铁矿物.

Representative susceptibility-temperature ( K-T) curves show 200~ 350 ℃ Curie temperature in addition to 580 ℃ of magnetite which reveals the existence of iron sulphide ( greigite or pyrrhotite).

代表性沉积物样品的磁化率-温度（K-T）曲线除了存在580℃磁铁矿的居里温度之外，还显示200~350℃的居里温度，指示样品中存在铁硫化物（胶黄铁矿-磁黄铁矿）。
