哈萨克斯坦地浸采铀生产现状与进展

Introduction to the status and development of in-situ leaching mines in Kazakstan

摘要: 地浸采铀具有生产成本低、建设周期短、环境友好等优点,其占世界天然铀总产量的份额逐渐增加。本文主要介绍了哈萨克斯坦的铀资源状况与天然铀生产状况,并在此基础上叙述了铀矿山的酸法地浸生产工艺。哈萨克斯坦作为世界上最大的天然铀生产国,地浸矿山是其天然铀的主要来源。国内在6个省份已探明50多个铀矿床,可地浸铀资源占世界总量的89%。18个地浸矿山正在开采,2012年总产铀量达到20900t。

Abstract: Due to the advantages of low operating cost,short construction period and friendly environment,the proportion of uranium produced by in-situ leaching mines increased year by year.Some techniques and parameters of acid in-situ leaching mines are shown on the basis of introducing uranium deposits and uranium production in Kazakhstan.As the largest uranium producer,in-situ leaching mines are the main source.50 uranium deposits were discovered in 6provinces,the resources amenable to in-situ leaching occupies up 89% of the total world resources.18in-situ leaching mines gave 20900 tU in 2012.
