FIELD: metallurgy.
SUBSTANCE: zinc-iron-bearing dusts are formed to the pellets by rolling with carbon reducing agent added to the charge as the suspension in the acetic solution with concentration of 3-10 wt %. High-temperature treatment is performed in the annealing furnace at 900-1100°C by the feed of heat carrier, extraction and catching of zinc oxide.
EFFECT: higher wettability of the charge, formation of extra surface bonds, dust particles are agglomerated to get the solid pellets.
