摘要
我国黄金矿山每年排放的数千万吨尾矿,占据大量土地,污染大气、水体,破坏植被,威胁生物生存.因此,尾矿的开发利用对于保护生态环境,提高黄金行业的综合经济效益和社会效益具有重要意义.依据黄金矿山尾矿中所含矿物成份的价值,将其分为以下四类:(1)含金量偏高,具有再回收前景;(2)可综合回收其它有价元素;(3)可作为其它工业原料;(4)目前尚无开发利用价值.并对各类尾矿的开发利用途径分别进行了评述,提出了加快黄金矿山尾矿开发利用的建议.
Millions of tons of tailings from processing plants in gold mines are produced each year. Dsposal of the tailings occupies large areas of farm land, pollutes air and water resources, damages vegetation, and endangers animal species. Therefore,utilization of these tailings plays an important role in protecting the environment and enhancing the social benefit of the gold industry. Tailings in gold mines are first classified into four types: (1 ) high grade tailings that may be reprocessed in the future. (2) tailings containing other valued elements, (3) tailings that may be used as raw materials, and (4) tailings without present utilization value.Utilization approaches for each type of tailings are discussed and suggestion is made on how to uti1ize tailings further.
