评价可地浸硬岩铀矿床的主要依据

作者根据国内外进行铀矿床原地破碎浸出工业试验的研究成果，总结了判别硬岩铀矿床能否适于地浸的主要依据，内容包括矿石的破碎性能、矿石的浸出性能、矿石的渗透性及围岩的透水性。并认为只有在全面分析与主要判据有关的矿床地质因素、水文地质因素的基础上，才能从技术可行性方面分析矿床能否适于地浸。

MAIN BASIS FOR THE EVALUATION ON IN-SITU LEACHING FEASIBILITY OF URANIUM DEPOSITS IN HARD ROCKS

In terms of the research results from the industrial tests on in-situ ore crushing /leaching of uranium deposits at home and abroad, main criteria that have been summarized to discriminate whether the uranium deposit in hard rocks is suitable for in-situ leaching by the author include: the crushing behaviour, the leaching behaviour and the permeability of the ores and the water permeability of the wall rocks. The author considers that only on the basis that the geological factors and hydrogeological factors in the deposit related with the essential criteria have been comprehensively analysed, can the suitability of the uranium deposit for in-situ leaching in the aspect of technical feasibility be analysed.
