| 摘 要： | 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。助渗剂以表面活性剂为主体,目的是提高溶浸剂的渗透性和浸出工艺的效率。经对多种硬岩矿和泥矿的试验,证明其效果明显。还对助渗剂的作用机理作了初步探讨。

| Abstract: | 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.The permeation-promoters are added,which consist of different surfactants,to increase the permeability of fluid and the leaching efficiency.After several tests in hard-rock ores and muddy ores,it has been proved that the effect of permeation-promoter is remarkable.The priciple of permeation-promoter is discussed as well. |
