摘要
对南京市现有金属和化工非金属矿山的现状进行了统计分析，对不同矿山的经济潜力进行了评估．重点分析，讨论了金属矿山共（伴）生矿种和尾矿综合利用的经济价值和环境效益．共（伴）生矿种的综合利用，可以提炼多种有用元素，其选冶价值很高，产生的经济效益十分显著，或作为建筑材料，更重要的是可以解决尾矿堆存所造成的环境污染以及占用土地等巨大公害问题．最后对影响南京矿山企业开展综合利用的不利因素进行了分析．
We present the result of an investigation of the actural situation of metalliferous and chemical mines in the area of Nanjing, and of an evaluation of the economic potentialities of all different types of mines. Especially, the authors discussed the economic values and environmental effects of coexisting(or associated) ores and wastes in metalliferous mines. By comprehensive utilizations, many valuable metals may be extracted from coexisting (or associated) ores. Otherwisem mineral wastes may be utilized as building materials. Most importantly, comprehensive utilixations of minerals wastes can resolve the grave public problem of environmental pollution and land occupy. Finally, the authors discussed factors unfavourable to the comprehensive utilixations of mineral resources.
