  • Heat balance and material calculate of zinc smelting sludge was investigated in the field of the volatilized reaction characteristics of zinc and lead of smelting sludge. The result showed that zinc oxide dust was retrieved after zinc and lead volatilized at high temperature. The quantity of zinc in dust of baghouse system and cooling system were 65.9% and 29.4% of total zinc, respectively. The proportion was correspondingly 55.8% and 41.1% of total lead. Endothermic reaction system was primary in rotary kiln treating process of zinc smelting sludge. Chemical reaction heat was 63.0% of total heat and thermosteresis of the system was 8.4%. Consequently, a decrease in the reaction temperature could avoid the heat loss of water evaporation and slag discharge, and then reduced the thermal loss of process system.
