摘要： The invention concerns a facility (10) for purifying a material comprising an assembly (30) of crucibles (32, 36, 38; 132). Each crucible comprises a chamber intended to contain the material in the molten state and a discharge conduit for discharging the material in the molten state from the chamber. The assembly comprises at least first, second and third crucibles, the first crucible being at least partly directly above the second crucible, the discharge conduit of the first crucible opening into the second crucible and the second crucible being at least partly directly above the third crucible, the discharge conduit of the second crucible opening into the third crucible. The facility further comprises a heating system (40) which surrounds at least part of each crucible and a system (58) for recovering the material in the molten state supplied by the discharge conduit of one of the crucibles of said assembly.
