1. A method for determining a mining value of a leucogranite-hosted uranium deposit, comprising:
determining average uranium grade, uranium occurrence, average uranium recovery rate and uranium stripping ratio of a leucogranite-hosted uranium deposit in an exploration region, wherein the average uranium recovery rate is a ratio of a uranium recovery amount after hydrometallurgy to a total uranium amount, and the uranium stripping ratio is a ratio of an amount of rock to be stripped to a uranium ore amount in a mining process; and
determining a mining value of the leucogranite-hosted uranium deposit in the exploration region, wherein the mining value of the leucogranite-hosted uranium deposit is determined based on one or more of the average uranium grade, the uranium occurrence, the average uranium recovery rate, and the uranium stripping ratio,
wherein the determining a mining value of the leucogranite-hosted uranium deposit in the exploration region comprises:
determining that the leucogranite-hosted uranium deposit has a mining value, if following conditions are satisfied: the average uranium grade being greater than the first preset value, a proportion of a uranium whose uranium occurrence is uraninite and uranophane being greater than the second preset value, the average uranium recovery rate being greater than the third preset value, and the uranium stripping ratio being less than or equal to the fourth preset value
wherein the method further comprises:
determining an average niobium content and/or an average tantalum content of the leucogranite-hosted uranium deposit in the exploration region;
wherein the determining a mining value of the leucogranite-hosted uranium deposit in the exploration region further comprises:
determining that niobium and/or tantalum in the leucogranite-hosted uranium deposit has a value for mining as an associated resource, if it is determined that the leucogranite-hosted uranium deposit has a mining value and the average niobium content and/or the average tantalum content is greater than a fifth preset value;
wherein the method further comprises:
mining the niobium and/or tantalum together with the uranium in the leucogranite-hosted uranium deposit, so as to maximize the utilization of resources.
