INCREASE IN FLOW RATE OF EXTRACTION WELLS DURING URANIUM LEACHING USING A CHEMICAL REAGENT

https://doi.org/10.48498/minmag.2023.218.6.005

The article presents the results of the study and analysis of the mining and geological features of the object of study, which made it possible to identify the main reason for the decrease in the flow rate of pumping wells due to the colmatation of filters and the filter part of wells due to the predominance of silicon compounds in the array. Therefore, the technology of decolmatization of filters and the filter part of wells is proposed and the results of pilot work to increase the flow rate of pumping wells during underground borehole leaching of uranium using ammonium bifluoride are presented. Comparative results before and after treatment of the leaching solution with ammonium bifluoride showed that the flow rate of various pumping wells increased from 1.4 to 4.4 m³/h, and in others – from 2 to 5.3 m³/h.
