PROBLEM TO BE SOLVED: To provide a device and a method and a device for inerting toxic materials by plasma melting comprising a melting chamber (1) having an internal volume bounded by walls. SOLUTION: The device comprises at least one of non-transferred arc plasma sources (8, 9) designed to generate a plasma jet that is inclined towards the lower part of the melting chamber (1), by propagating along propagation axes (17, 18) lying out of the vertical plane (P). The vertical plane (P) contains the normal to the wall at the point of intersection (20) between the propagation axes (17, 18) and the wall (4), so as to stir the melt bath (6). The melting chamber (1) is in fluid communication with the upstream part of a refining and casting chamber (26). The latter refining and casting chamber (26) includes, in its downstream part, a port to which a non-transferred arc plasma source (30) is connected. This source (30) is mounted so as to emit a plasma jet (31) in order to strike the refining bath (27) directly in the upstream part so as to repel the unmelted elements in the melt bath (6).
