Embodiment
[0046] The invention provides a sandstone type uranium ore CO 2 +O 2 The reaction migration numerical simulation method of in-situ leaching mining uranium, the embodiment of the present invention takes a certain uranium deposit CO 2 +O 2 Indoor pressurized column immersion test as an example.
[0047] 1) CO 2 +O 2 Pressure column immersion test conditions
[0048] CO is generally carried out before industrial in-situ leaching mining 2 +O 2 Suitability Pressurized column leaching indoor test work, leaching uranium test simulation under pressure conditions can obtain a series of in-situ leaching process parameters, and provide reference for industrial mining design. Experimental column immersion simulation device such as figure 1 shown, including compressed gas bottles, leaching columns, samplers and solution circulation pumps, etc. For specific instructions, please refer to relevant literature. During the test, first analyze and identify the core ore sample taken in th...
