研究获知,我国铀矿山出坑矿石的品位(以矿车为统计单元)是对数正态分布的。本文应用这一品位分布规律开拓了确定堆浸品位下限及水冶品位下限的计算方法。
Study found that China’s uranium mine pit ore grade (with tub as a statistical unit) is logarithmically normal distribution. In this paper, the application of this grade distribution rule opens up the calculation method for determining the lower limit of heap leaching grade and the lower limit of hydrometallurgical grade.
