This study investigates the flotation-based enrichment of black shale raw materials to selectively separate uranium and rare earth metals (REMs). The efficiency of various reagent systems-xanthogenate, kerosine, and paraffin with trichloroisocyanuric acid (TCCA)-was examined under different grinding fineness conditions. The initial material showed significant concentrations of uranium (0.188%) and REMs, with carbon content reaching up to 15%. The highest uranium removal (up to 98%) into mineral tailings was achiev...
