FIELD: non-ferrous metallurgy; production of metals by distillation method.
SUBSTANCE: proposed method includes vacuum distillation of calcium from copper-calcium alloy performed in shaft furnace at six-hour cycle; power of furnace is distributed in height of shaft in accordance with reduction of level of melt in evaporator; reduction of mass fraction of calcium in melt residue is limited to 25-30%.
EFFECT: reduced specific power requirements; reduced usage of materials.
