中文摘要: 某大型矿冶集团针对该集团铜尾矿库尾矿大量堆存,安全环境风险突出,新建尾矿库选址困难、尾矿消纳途径有限等问题,通过长期摸索研究和对铜尾矿库尾矿粒径分布、成分、化学属性、浸出毒性和放射性等因素进行分析,探索出通过胶凝改造技术充填、制备公路工程无机结合料和铜尾矿资源脱硫分级综合利用的低碳材料消纳模式,尾矿库尾砂能够全粒径规模化消纳利用。单位产品分别消纳尾矿0.075t/t、0.1275 t/t和1t/t,降碳1.564t/t、0.054t/t和0.5195t/t,并分别具有40.0971元/t、12.1235元/t和14.4653元/t的环境正效益,同时协同处置了大量其他固体废物,真正实现了铜尾矿全粒径规模化增值消纳,在全国范围内有很好的借鉴意义。
Abstract:A large mining and metallurgy group aims at the problems of massive stockpiling of tailings in the group''s copper tailings pond, prominent safety and environmental risks, difficult site selection of new tailings pond, limited ways to absorb tailings, etc. through long-term exploratory research and analysis of factors such as particle size distribution, composition, chemical properties, leaching toxicity and radioactivity of tailings in the copper tailings pond, it explores how to fill preparation of inorganic binder for highway engineering and low-carbon material consumption mode of desulfurization, classification and comprehensive utilization of copper tailings resources. Tailings of tailings pond can be consumed and utilized on a large scale with full particle size. The unit product can adsorb tailings of 0.075t/t, 0.1275 t/t and 1t/t, reduce carbon by 1.564t/t, 0.054t/t and 0.5195t/t respectively, and has positive environmenta benefits of 40.0971 yuan /t, 12.1235 yuan /t and 14.4653 yuan /t. It also cooperates with the disposal of a large number of other solid wastes, and truly realizes the full particle size standardized value-added consumption of copper tailings, which has a good reference significance nationwide.
