栾川县尾矿综合利用研究进展

Research Progress on Comprehensive Utilization of Tailings in Luanchuan County

栾川县矿产资源丰富,尾矿库较多。结合栾川县尾矿库调查结果,综述钼钨、铅锌、金和铁等类型的尾矿综合利用研究进展,并提出尾矿综合利用的优化策略,为矿山固体废弃物的资源化、减量化与无害化处置提供技术指导。目前,尾矿综合利用方式主要有3种,即有价金属元素提取、有价非金属元素提取和尾矿建材化利用。未来,要加大科研投入,开发新型尾矿综合利用工艺;推进尾矿原位回填,修复区域生态环境;强化梯级利用,实现尾矿全部消纳。

Luanchuan county is rich in mineral resources and has many tailings ponds.Based on the investigation results of the tailings pond in Luanchuan county,the research progress is summarized on the comprehensive utilization of molybdenum tungsten,lead zinc,gold,and iron tailings,and the optimization strategies are proposed for the comprehensive utilization of tailings,thus providing technical guidance for the resource utilization,reduction,and harmless disposal of solid waste in mines.At present,there are three main ways of comprehensive utilization of tailings,namely valuable metal element extraction,valuable nonmetallic element extraction,and tailings building material utilization.In the future,it is necessary to increase research investment and develop new comprehensive utilization processes for tailings;promote in-situ backfilling of tailings and restore the regional ecological environment;strengthen cascade utilization and achieve complete consumption of tailings.
