Abstract: This article by laboratory test, study clay bearing uranium ore properties of Jiangxi, fraction composition, distribution of uranium, leaching properties of uranium ore, ore pulp leaching performance, etc.The fine clay of ore account for samples total weight of 30% or so, fine clay high grade with U, it cannot directly use heap leaching method.Fine clay slurry subsidence poor performance, solid-liquid separation difficulties.In certain conditions, ore samples in U of leaching 87.5%.To study the process of uranium ore recovery test to provide reference.
