摘要
本文从原地破碎浸出法采矿工艺流程出发 ,对 3 2 2铀矿田碎裂蚀变花岗岩型铀矿床 (点 )的各项成本要素进行了研究 ,建立了原地破碎浸出经济评价模型 ,引入了铀浸出率和回收率调整系数。利用原地爆破筑堆试验及一系列铀矿柱浸工艺试验获得的原地破碎浸出经济分析参数及经济评价模型对3 2 2矿田铀矿床原地破碎浸出进行了经济评估。
Using technical flow of in situ crushing leaching mining method, the authors analyze its cost items and introduce 2 adjusting parameters, namely the adjusting parameter for leaching rate of uranium and the adjusting parameter for recovery rate of uranium and establish an economic evaluation model of in situ crushing leaching mining for cataclastic altered granite type uranium deposits in ore field No.322. At the same time,the economic features are assessed by the economic evaluation model through a great number of economic analysis parameters obtained by both a blasting stacking test and a series of uranium column extracting tests.
