桃山矿田低品位铀资源开发利用前景

通过对桃山矿田地理交通条件、各矿床铀资源可靠性、矿床开采技术条件、矿石水冶性能、环境影响条件等分析,提出对桃山矿田6个矿床按绿色铀矿山建设标准要求和区域开发模式,以规模化、集约化的建设思路进行开发,以大布铀矿床为中心,建设中心水冶厂;采用原地爆破浸出技术,最大限度地减少矿石、废石外排,实现无废开采;通过合理确定矿床开采边界品位,实现高效开采;利用放射性选矿技术,减少出窿矿石处理量。通过采用新模式、新技术,可降低开发成本,提高资源利用率,实现对桃山矿田低品位铀资源高效利用。

Prospect of Exploitation and Utilization of Low-grade Uranium Resources in Taoshan Ore Field

Based on the analysis of the geographical traffic conditions of the Taoshan ore field,the reliability of uranium resources of each deposit,the mining technical conditions,the hydrometallurgy performance of ore and the environmental impact conditions,the construction idea of large-scale and intensive development of six deposits in Taoshan ore field according to the regional development mode is put forward.Taking Dabu deposit as the center,the central hydrometallurgy plant should be built.Underground mining adopts in-situ blasting leaching technology to minimize the discharge of ore and waste rock and realize no waste mining.By determining the mining boundary grade reasonably,efficient mining can be realized.Using radioactive mineral processing technology,the amount of ore produced can be reduced.Through the new model and new technology,the development cost can be reduced,the resource utilization rate can be improved,and the efficient utilization of low-grade uranium resources in Taoshan ore field can be realized.
