某复杂多金属矿低尾化综合利用技术研究

矿产资源在选矿过程中产生的大量尾矿,既是资源的浪费,又是环境污染源。因此,开展低尾化乃至无尾化综合利用研究,最大程度提高资源利用率是未来矿产资源开发、利用的必由之路。本文在研究国内某复杂多金属矿综合利用时,通过分析所含矿物的基因属性、赋存状态以及嵌布关系,先后进行了钽铌精矿、方解石精矿、锂精矿、云母精矿、长石精矿、石英精矿共计6个产品的选别回收,实现了除少量泥质、铁屑之外的全产品、无尾化综合利用技术路线,可为以后同类型复杂多金属矿的综合回收提供思路借鉴。

Research on comprehensive utilization technology of low tailing on a complex polymetallic ore

A large number of tailings produced by mineral resources in the process of mineral processing are not only a waste of resource, but also environmental pollution sources. Therefore, it is the only way to develop and utilize mineral resources in the future to study the comprehensive utilization of low tailings and even untailings. Based on the study of comprehensive utilization of a domestic polymetallic complex ore, through the analysis of the gene properties, occurrence state and disseminated relationship of contained minerals, tantalum niobium mineral, spodumene, calcite, mica, feldspar and quartz, a total of six products, are recycled successively, implementing all comprehensive utilization technology route except a small amount of clay, iron products, which provides a thinking model for comprehensive recovery of the same kind of complex polymetallic ore in the future.
