| Abstract: |
| Fankou Lead-Zinc Mine has done many experiments on comprehensive utilization of industrial wastes and achieved a great deal of achievements in utilization of industrial wastes. In this paper, some technologies in utilization of solid wastes are introduced, such as using the tailings as the cemented backfill material and refilling mullock into mined-out areas. The utilization of tailings is up to 40 percent and amount of mullock refilled annually into the mined-out areas underground up to 40000 cubic meters. As a result of technological improvement in mineral processing, the taillings yield is reduced by 10 percent, that is to say, tailings of 120000 tons is reduced annually. On the other hand, wastewater can be re-utilized by blocking fissure water and treating the industrial wastewater. The above measures have a great promotion to the development and progress of Fankou Lead Zinc Mine, obtaining obvious achievements in environment protection. For this reason, it has been reputed as a garden-like mine. |
