下庄地区“交点”型铀矿床的经济可采性探讨

Discussion on economic amenability of "intersection"-type uranium deposit in Xiazhuang area

本文叙述了下庄地区“交点”型铀矿床的地质特征和空间分布特点 ,从经济地质的观点 ,认为下庄“交点”型铀矿床矿体集中、埋藏浅、有一定储量、且矿石组分简单、品位富、铀浸出率高 ,有良好的开采利用前景。作者通过矿石加工试验及吨金属成本计算 ,进行了经济技术评价 ,认为该类型铀矿床应列为经济可采的矿床范围 ,及早开采利用。

Geologic characteristics and spatial distribution of 'intersection' type uranium deposits in Xiazhuang area are introduced in this paper.From the point view of economic geology it is suggested that orebodies in intersection type uranium deposits are characterized by concentrated distribution,shallow buried depth,certain amount of reserves,as well as simple ore composition,high grade and high leachability of uranium,and possess good potential for mining.Based on technological tests of uranium ores and the calculation of recovery cost of uranium metal the author makes economic technological evaluation of such deposits,and suggests that'intersection' type uranium deposits should be attributed to economically amenable deposits and should be put into mining and development.
