摘要： The disclosure relates to a beneficiation process for low grade uranium ore, wherein the process comprises a primary beneficiation stage comprising: wet scrubbing the low grade uranium ore to separate the low grade ore into a fine fraction and a coarse fraction; screening the fine fraction according to a size separation parameter to provide an undersize fraction and an oversize fraction, wherein the uranium predominantly reports to the undersize fraction; and separating the undersize fraction to produce an intermediate uranium concentrate. The intermediate uranium concentrate may be further processed in a secondary beneficiation stage to produce a high grade uranium concentrate.

摘要： The invention relates to a beneficiation process for uranium ores comprising clay and carbonate minerals, the process comprising: performing a hydrocyclone step to obtain a hydrocyclone underflow fraction substantially comprising the uranium component; treating the hydrocyclone underflow fraction to effect a separation of carbonate and uranium minerals; and recovering the uranium-bearing minerals to produce a uranium concentrate.

摘要翻译： 本公开涉及低等级铀矿石的选矿方法，其中该方法包括主要选矿阶段，包括：湿法洗涤低品位铀矿石以将低品位矿石分离成细级馏分和粗级分; 根据尺寸分离参数筛选细分，以提供过小部分和过大分数，其中铀主要报告给过小部分; 并分离过小的馏分以产生中间体铀浓缩物。 中间铀浓缩物可以在二次选矿阶段进一步处理，以生产高品位铀浓缩物。
