Abstract: The concentrator of Meishan Mining Co. produces annually about 0.85 million t fine tailings and the existing tailings reservoir capacity will sustain six years' production. It has become an urgent issue to realize a comprehensive utilization of the fine-sized tailings. Therefore, Meishan Mining Co. has carried out in recent years a great deal of work in this respect and has achieved certain progress, including enhancing the thickening-dewatering of the fine-sized tailing, reducing its metal loss and researching and developing new building materials with the fine-sized tailings as the raw material.

Key words: Fine-sized tailing, Comprehensive utilization, Dewatering by thickening, Tailing re-concentration, New type building material
