Technical characteristics and optimum application conditions of in-situ leaching of uranium ore body

Based on theoretical studies and field tests of in-situ leaching of uranium ore body, it is found that the method has very important technical characteristics that the height of heap is extraordinarily high, the shape of heap is irregular, the heap site is enclosed and hidden beneath the surface, the ore can only be fragmented for one time, the fragment size and composition are very important, and the measures to prevent underground pollution have to be taken necessarily. These technical characteristics have to be taken into account and comprehensive quantitative studies have to be conducted in accordance with the criteria of whether the application conditions are very favourable, favourable or unfavourable before the decision is made to adopt the in-situ leaching method
