The method is used in metallurgy in the processing of scrapcontaining nonferrous metals, in particular zinc. By it materialis produced suitable for its subsequent treatment in electric arcfurnace by the evaporation of the zinc in a condenser. The zinccase is charged with fluxes and carbon-container restorer. Theproduced charge is subjected to agglomeration at temperature rangefrom 1200 to 1300°C for 12 to 20 min.1 claim
