一般,原地浸出采矿法适用于不同形态与成因类型的具有疏松结构的砂岩型铀矿床。 在美国,这类可地浸的砂岩型铀矿被称为卷形砂岩型铀矿床。美国铀矿业界给出的函义是——沿砂岩主岩,蚀变与未蚀变界面后生成因的还原铀矿和其他各种矿物的聚集体。矿体一般横切主岩,也有与主岩沉积呈准整合关系的。矿体横切面是“C”形,其中也有呈不规则状的。这类矿床很明显是由氧化的地下水形成的,即当含氧携铀的地下水,在渗透和运移进程中被砂岩中的硫化物有机质和其他矿物的氧化而将
In general, the in-situ leaching method is applicable to loose-structured sandstone-type uranium deposits of different morphologies and genetic types. In the United States, such in-leachable sandstone-type uranium deposits are known as coiled sandstone-type uranium deposits. The message given by the uranium industry in the United States is - aggregates of reduced uranium and other minerals that originate along the main sandstone, alteration and non-alteration interfaces. The ore body generally traverses the main rock and also has a semi-integrated relationship with the host rock. The cross section of the ore body is “C” shape, which also has irregular shape. Such deposits are clearly formed from oxidized groundwater, that is, when the groundwater containing oxygen-carrying uranium is oxidized by the sulfide organic matter and other minerals in the sandstone during its infiltration and transport processes
