1. A method for breaking an electrolyte crust by a separation cutting in a reduction cell for production of an aluminum, the method comprising:

  • (a) thermally melting a crust material with a high-speed high-temperature concentrated flow of a thermal plasma jet heat energy, wherein a directed thermal plasma jet is generated and moved above the electrolyte crust along a predetermined; and

    (b) continuously removing a formed molten material from a zone of the thermal plasma jet impact to create a slit in the electrolyte crust with the thermal plasma jet, wherein the slit is enough to perform the separation cutting and the breaking of the electrolyte crust.
