[en] Uranium extraction from the LiF-BeF₂ melt, containing 0.2 mol.% UF₄, by bismuth-lithium alloy at temperatures 600 to 655 deg has been studied. Linear dependence is obtained of the uranium distribution coefficient at a temperature of 650 deg on the lithium distribution coefficient, with the angular coefficient close to three. At 600 deg the Dsub(U) value reaches 2x10² at the lithium concentration in the alloy of about 1 at.%. Under these conditions separation of uranium from rare earth elements with separation factor 100-200 is possible
