FIELD: non-ferrous metal metallurgy. SUBSTANCE: cakes of sewage purification containing non-ferrous metals are processed by calcination together with concentrate of nickel sulfide. The process takes place in fluidized bed furnace, it is followed by reduction and melting cinder to anode nickel. Pitch content in mixture is 1-5 mass % of nickel. EFFECT: increases recovery degree of non-ferrous metals, improves technical and economy indexes of the process. 2 tbl
