铜陵地区黄金矿山尾矿资源的综合利用

COMPREHENSIVE UTILIZATION OF THE GOLD MINE TAILINGS RESOURCES IN THE TONGLING AREA

随着黄金开发规模的扩大和开采历史的延长,黄金矿山尾矿多采用库存方式处理,尾矿堆积量逐年增加,不仅占用大量的土地,造成库区周围环境污染,而且还需要投入大量的资金用于尾矿库的修筑和维护管理工作。因此,对于1g/t左右的黄金矿山尾矿的综合利用,已成为各黄金矿山资源综合利用和环境的工作重点之一。铜陵地区的黄金资源开发,随着矿山开采年代久远,高品位矿石已成下降趋势,因此对往日排弃的尾矿显得重视起来。我公司通过对这种排弃的尾矿勘查、研究,经过经济分析,大部分尾矿具有较好的经济价值。对于这种不可再生的矿产资源的研究,为今后的黄金矿山可持续发展、资源综合利用及生态环境保护提供了科学依据。

With the expansion of development scale and extension of mining time for gold the mine tailings as treated by storage have increased year after year not only taking up much of the land causing pollution to the environment around the reservoir but also needing to expend a lot of money for construction and maintenance of the tailings reservoir. Therefore, utilization of gold mine tailings of around 1g/t has become one of the priorities given to comprehensive utilization of the resources and to environmental protection. With the time going the long developed gold resources have shown a decreasing trend for high-grade ores in the Tongling area. So it＇s time for paying attention to the tailings abandoned in the past. After economic analysis of the tailings, we found that the majority of the tailings have good economic value. For these non-renewable mineral resources, this research has provided a scientific basis for sustainable development of gold mines, comprehensive utilization of the resources and protection of the ecological environment.
