Embodiment 1
[0037] A method for calculating the relationship between clay minerals and uranium mineralization in sandstone-type uranium deposits, including the following steps:
[0038] Step 1: Select core samples with the oxidation zone, transition zone, and reduction zone of the interlayer oxidation zone sandstone-type uranium deposit as different subzones, and calculate the core sample quality of the three subzones as Q 1 , Q 2 , Q 3 , Calculate the uranium content of the core samples of the three subzones as U 1 , U 2 , U 3 ;
[0039] Step 2: Separate and purify the clay minerals in the three subzone core samples, and calculate the quality of the separated clay minerals as MQ 1 , MQ 2 , MQ 3 ;
[0040] Step 3: Analyze the types, compositions and properties of clay minerals in the three subzone core samples;
[0041] Step 4: Calculate the uranium content of the clay minerals in the three subzone core samples as BU 1 , BU 2 , BU 3 ; Calculate the uranium content U of the core samples of the thre...
Embodiment 2
[0047] On the basis of Example 1, the most favorable adsorption conditions in step 5 can be obtained by the following steps:
[0048] Step 5.1, select typical mineral standard samples with the same properties according to the type of clay minerals obtained in step 3, and perform adsorption reaction experiments of typical mineral standard samples on uranium hexavalent in uranyl nitrate under different acid-base conditions, and compare the same clay minerals The type of adsorption rate under different pH conditions.
[0049] Step 5.2: Perform adsorption reaction experiments of typical mineral standard samples in uranyl nitrate solutions with different initial concentrations, and compare the adsorption rates of the same clay mineral type under different initial solution concentrations.
[0050] Step 5.3, under the conditions of the same pH value and initial solution concentration, use different types of typical mineral standards to conduct adsorption reaction experiments on uranium hexa...
Embodiment 3
[0053] On the basis of Example 1 or Example 2, for the purification of clay minerals in step 2, the freezing temperature method can be used, which specifically includes:
[0054] Step 2.1, crush the core sample into small pieces, wash off the powder adsorbed on the surface of the pieces with deionized water, soak the core sample with deionized water, seal it and put it in the freezing-thawing device;
[0055] Step 2.2, repeatedly freeze-thaw the broken sample;
[0056] Step 2.3, processing of chemical samples of samples;
[0057] (1) Remove carbonate and replaceable calcium and magnesium ions.
[0058] (2) Remove iron oxide and iron hydroxide;
[0059] (3) Remove silica;
[0060] Step 2.4, wash off Cl - , Mg 2+ , Ca 2+ , HCl;
[0061] Step 2.5, prepare the suspension: add concentrated ammonium hydroxide dispersant, add deionized water and stir gently, and stand still.
[0062] Step 2.6, use sedimentation siphon method, centrifugal separation method and microporous membrane filtration method...
