Embodiment Construction

[0038] The technical solutions of the present invention will be described in detail below in conjunction with specific embodiments.

[0039] A kind of uranium-molybdenum ore standard substance preparation method of the present invention comprises the following steps:

[0040] (1) Select a variety of uranium-molybdenum metal ores with the same wall rock type, and the non-metallic components in the ores include quartz, calcite, fluorspar, and apatite;

[0041] In the uranium-molybdenum metal ore, the mass content of silicon dioxide is 30%-80%, the mass content of ferric oxide is 2%-10%, the mass content of uranium is 0.01%-0.3%, and the mass content of molybdenum is 0.01% %-1%;

[0042] The host rock type of uranium-molybdenum metal ore is one of the following two types: volcanic rock type and sandstone type; in uranium-molybdenum metal ore, the ore structure and structural features are mainly disseminated ore; the main forms of uranium-molybdenum metal minerals are: The types...

Abstract

The invention belongs to the technical field of standard substance preparation, and particularly relates to a preparation method of a uranium-molybdenum ore standard substance. The invention providesa method for preparing the uranium-molybdenum ore standard substance. Under the condition that the development requirements of the standard substance are met, the problems that the uranium-molybdenumproportion is not suitable, and characteristic elements are lost are solved, and the uranium-molybdenum ore standard substance meeting the technical indexes is finally prepared through verification ofuniformity, stability and the like. According to the scheme, uranium ores with different contents and different places which are volcanic rock ores and uranium ore as main materials are selected, andpreparation is carried out according to a certain proportion, so that the preparation of the ore standard substance is not limited to searching a single ore candidate, the standard substance is obtained through an actual fixed value result, the uranium ore standard substances with different contents can be obtained through preparation, and the problem that the uranium ore standard substances aredifficult to reproduce is solved.

Description

technical field [0001] The invention belongs to the technical field of standard substance preparation, and in particular relates to a method for preparing a uranium-molybdenum ore standard substance. Background technique [0002] Among the existing uranium resources in our country, some belong to uranium-molybdenum associated ores, among which uranium reserves account for more than 10% of the total reserves, which is an indispensable part in the development of uranium resources in our country. In recent years, my country has also carried out a large number of experimental research work on the comprehensive recovery of uranium and molybdenum ore. The technology of extracting uranium and molybdenum from uranium and molybdenum associated ore is becoming more and more mature. Some mines are about to be industrialized, and others are undergoing process tests. The associated ores of uranium and molybdenum are widely distributed in my country, and they exist in volcanic rocks, gran...
