Abstract (en)
[origin: US4525207A] Calcine which has been obtained by roasting in a fluidized bed and contains zinc oxide is briquetted at elevated temperatures. To produce briquettes having desirable properties for processing in a zinc-producing shaft furnace, the calcine is provided with metallic lead and/or lead oxide in an amount corresponding to at least 3% lead, non-caking coal having a low content of volatile constituents is admixed to the calcine, the Pb:C weight ratio is adjusted to at least 1, and the mixture is briquetted at a compacting temperature of 250 DEG to 470 DEG C. and under an applied pressure amounting to 4 to 20 metric tons per centimeter or roll width when said pressure is dynamically measured.
