钼矿排土场废石综合利用研究

Comprehensive Utilization of Waste Rock in a Molybdenum Mine Dump in Shaanxi Province

针对陕西某钼矿排土场废石,在化学成分分析、岩矿性能测试、放射性检测等多项测试分析的基础上,本文确定了该钼矿排土场废石综合利用方案。其间通过移动式重型除土振动筛、移动颚式破碎机、圆锥破碎机和移动式分级振动筛的机组联合,采用"预先除土-两段一闭路破碎"生产工艺,获得了三种不同粒径的高品质建筑骨料,为同类型废石的综合利用提供借鉴与参考。

Aiming at the waste rock of a molybdenum mine dump in Shaanxi,based on the chemical composition analysis,rock and mineral performance testing,radioactivity detection and other tests and analysis,this paper determined the comprehensive utilization plan of the molybdenum dump waste rock.In the meantime,through the combination of mobile heavy-duty soil removal vibrating screen,mobile jaw crusher,cone crusher and mobile grading vibrating screen,the production process of"pre soil removal-two stages and one closed-circuit crushing"was adopted to obtain three different high-quality construction aggregate with particle size,which could provide reference for the comprehensive utilization of the same type of waste rock.
