FIELD: special electrometallurgy processes, namely electroslag refining, possibly making cast articles, mainly of compact waste material of copper and(or) its alloys. SUBSTANCE: method comprises steps of electroslag refining of consumable electrode and forming ingot in stationary water cooled crystallizer in the form of truncated cone. Diameter of upper base of truncated cone consists 0.85-0.98 of diameter of its lower base, height of crystallizer consists 3-7 of lower base diameter. At melting process gap between walls of crystallizer along its whole perimeter and consumable electrode is maintained equal at least to 15 mm. EFFECT: enhanced stability of electroslag refining process, improved quality of ingot made of compact waste material, mainly of copper and(or) its alloys. 7 cl, 1 ex
