摘　　要：利用堆浸尾矿渣进行配矿后再选，回收其中的有益元素。利用去毒化处理的尾矿浆通过溢流方式，由管路输入人工砌筑的封闭的围堰内，矿浆经沉淀、自然脱水后形成固态化土壤。对尾矿形成的人工土壤利用植物修复技术逐步消除其重金属元素，形成清洁无污染的人工农田，从而达到造田的目的。本试验在嵩县境内同类型金尾矿的综合利用中独辟蹊径，起到了良好的示范作用。Using heap leaching tailings of ore blending after the reelection, the recovery of useful elements. To poison the processing and utilization of tailing pulp by flooding, by pipeline input artificial masonry enclosed cofferdam, pulp through precipitation, natural dehydrated to form solid soil. The formation of tailings artificial soil using phytoremediation to gradually eliminate the contents of heavy metal elements, artificial farmland forming a clean and pollution-free, so as to achieve the purpose of farmland. The test for the comprehensive utilization of the territory of Songxian the same type of gold ore tailings inventive, and played a good role model.
