铀矿

Based on the analysis of the origin of uranium, lithogeochemical zonations are subdivided.

在分析铀矿成因的基础上，将岩石地球化学进行了分带。

In this paper the situation of commercial application on bacterial heap leaching in Ganzhou Uranium Mine is introduced,and the construction of biomembrane oxidizing tank, regeneration and recycled utilization of barren solution are summarized.

报道了赣州铀矿某分矿细菌堆浸工业化应用的概况，并介绍了生物接触氧化槽的结构和吸附尾液氧化再生循环利用的具体措施。

In the heap leaching process of uranium ores some problems often occur,such as permeability declining and/or the blockage of penetrating holes,which are caused by muddled ores,expanded ores and the migration of fine particles.

在某些铀矿堆浸工艺中，由于矿石的泥化、膨胀和细颗粒迁移等原因，经常出现通道堵塞、渗透率低的问题，为此，提出了添加助渗剂的方案。

The permeability of ore mass has a great influence on the leaching period of heap leaching and the leaching efficiency,hence the uranium ore s with high content of clay is difficult to acidic heap leaching.

矿堆的低渗透性能是局限矿石浸出周期及金属浸出率的最主要因素之一，因此，长期以来，高含泥量的铀矿石一直是酸法堆浸提铀技术的应用禁区。

Through analysis of geological setting of ore beds and considering the prerequisite of heap leaching mining, the Pliocene of Kuqa-Ertatai area is predicted to be a prospect area of placer-type uranium mineralization.

通过对各含矿层地质背景分析，并考虑到地浸开采的前提条件，预测出库车－二八台地区上新统为可供地浸的砂岩型铀矿成矿远景区。

In order to increase the permeability coefficient of the ore mass, achieve the: homogenous penetration for whole leap by improvement of the particle size and is distribution, the factors influencing on the heap leaching with agglomeration for the cracked granite uranium ore are investigated.

研究渗透性差的破碎花岗岩型铀矿石制粒堆浸过程的影响因素，通过改变矿石粒度及粒级分布，提高溶液通过堆浸矿石的渗透速率，有效地改善全矿堆渗透的均匀性。

I sat with uranists in the Deux Magots....

我和铀矿学家—起坐在&第二人像&里。

The decontaminating experiments of radioactive surface contamination are carried out with polymer mambrane decontaminating material which can be denuded at a uranium mill and with chemical decontaminating agent at a uranium mine.

介绍了在某铀水冶厂厂区内用可剥离聚合物成膜去污材料和在某铀矿用化学去污剂分别进行的放射性表面污染去污试验，讨论了试验结果，对我国铀矿冶放射性表面污染去污提出了建议。

A complex brownish - black mineral,UO2,forming the chief ore of uranium and containing variable amounts of radium,lead, thorium ,and other elements.

沥青铀矿黑褐色的合成矿，UO2，主矿为铀，还包括不定数量的镭、铅、钍和其他元素

And therefore we kept a very close eye, as governments do in their various ways, on Iraq trying to get hold of nuclear base materials, such as uranium or uranium yellowcake, or trying to get the machinery that was necessary to develop nuclear-weapons-grade material.

所以我们总是密切注意，政府会用各种不同的渠道，留意伊拉克试图得到核物料，如铀或者黄铀矿，或者试图获得加工核武器级别核原料的机器。

Do you know, i need you to come back
