Iron Tailing | Scientific

Abstract: Iron tailing is a kind of mineral waste from industrial processing and magnetic separation of iron ore, which severely pollute the air, soil property and the source of water. For large scale tailing ponds (dam height >100 m), the accident could cause a substantial damage. Therefore, it is significant to appropriately utilize the tailings.
