铀矿水冶过程中的加工费主要用于矿石的浸出,而浸出试剂费又是其中的主要费用。从已公布的资料看,铀水冶厂通常的浸出费用占水冶直接加工费用的50％左右,试剂消耗费用又占浸出费用的62％,因此,降低铀矿浸出试剂的消耗量是一个极其有意义的课题。 本文针对该矿石浸出特征,阐述了利用剩余酸返回进行两段逆流浸出,并与常规浸出比较,这种浸出法可降低用酸量30％左右。
The processing fee in uranium hydrometallurgy process is mainly used for ore leaching, and leaching reagent fee is one of the major expenses. According to published data, the common leaching costs of uranium watermelon plants account for about 50% of the direct processing costs of water and metallurgy and reagent consumption costs account for 62% of leaching costs. Therefore, reducing the consumption of uranium ore leaching reagents is an extremely important Meaningful topic. In this paper, leaching characteristics of the ore, described the use of residual acid back two countercurrent leaching, and compared with conventional leaching, this leaching method can reduce the amount of acid with about 30%.
