Method for separating and identifying bacteria in interlayer oxidation zone sandstone type uranium deposit

Abstract

The invention belongs to the technical field of geology, and particularly relates to a method for separating and identifying bacteria in an interlayer oxidation zone sandstone type uranium deposit. The method specifically comprises the following steps: determining the geological background of a research area, and determining whether a large number of microorganisms exist in typical uranium deposituranium ore or not; separating and observing strains in the ore; and extracting total bacteria in the ore. According to the invention, through the in-situ separation of the interlayer oxidation zonesandstone type uranium deposit bacteria, the types of special bacteria in the special mineralization environment of the typical uranium deposit are determined, the characteristics of the bacteria areresearched, the types of the bacteria and the microorganisms with high uranium ore enrichment capacity can be further found out, the contribution of different microorganisms to sandstone uranium ore mineralization is determined, the uranium ore forming environment is further determined, uranium ore prospecting is guided, and the ore prospecting cost is reduced. Meanwhile, the method can provide afeasible bacterial population for in-situ leaching uranium mining, provides a feasible and efficient bacterial liquid culture technology for a microbial ore leaching process, and reduces the mining cost.

Description

technical field [0001] The invention belongs to the technical field of geology, and in particular relates to a method for separating and identifying bacteria in sandstone-type uranium deposits in interlayer oxidation zones. Background technique [0002] At present, a large number of soil-born or stone-born microorganisms have been found in sediments and rocks, but the types of microorganisms and their metabolic activities related to uranium deposits, as well as the relationship between the distribution of these microorganisms and geology and geochemistry are still poorly understood. It has been confirmed through previous experiments and exploration that a certain amount of microorganisms do exist in the ores of the Shihongtan uranium deposit in the Turpan-Hami Basin. [0003] Therefore, it is necessary to carry out simulation experiments on the relationship between microorganisms and uranium mineralization in sandstone-type uranium deposits in interlayer oxidation zones, est...
