| Abstract: | 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. |
