FIELD: regeneration processes of secondary raw material, namely electrochemical processing of metallic waste material of rhenium or molybdenum.
SUBSTANCE: method comprises steps of processing waste material of rhenium or molybdenum in ammonia electrolytes while using waste material as electrode onto which alternating electric current of commercial frequency is applied. At processing operation small plates of tantalum or niobium are used as second electrode.
EFFECT: increased electric current yield due to prevention of occurring non-desirable secondary reactions.
