512铀矿床地浸条件及技术经济评价

IN-SITU LEACHING CONDITIONS AND TECHNICALECONOMICAL APPRAISAL OF URANIUM DEPOSIT NO. 512

本文应用铀矿普查及地浸试验中获取的资料，对５１２矿床地质构造、矿石物质成份、矿床水文地质、工程地质及自然经济地理等地浸条件及矿床技术经济条件进行了分析评价，认为５１２矿床地浸条件较好，地浸技术指标适中，用酸法地浸开采具有耗酸量少、成本低、经济效益好的特点。在今后的开采中，若能解决伴生元素Ｒｅ，Ｓｅ，Ｍｏ的综合利用问题，将会大大提高矿床的经济价值。

Using the data obtained from uranium prospecting and in-situ leaching mining experiments,this paper analyzes geologic structures, ore composition, hedrogeology, engineering geology, natural economy and geography and other in-situ leaching conditions of uranium deposit No. 512,andappraises the technologic and economical conditions of the deposit. The author concludes that insitu leaching conditions of the deposit are favourable with fair in-situ leaching techological index,and acid in-situ leaching mining will yield less acid consumption,low cost and high economic benefits. If the problem of comprehensive recovery of Re, Se, Mo and other associated elements can beresolved in the future mining,the economic value of the deposit will be greatly increased.
