Fig. 3 CSC process flow chart for complex materials containing lead
through the nozzle of the fuming furnace, the metal zinc in the reduction slag
is reduced to zinc steam, the zinc steam is oxidized at the third air outlet of the
fuming furnace, forming the secondary zinc oxide, the heat energy generated
during the period is recovered by the waste heat boiler, and the high-temperature
flue gas is sent to desulfurization after passing the waste heat boiler and dust
collection. After fuming and converting slag is sent to water for quenching, it
will be sold to cement plant. In the actual production process, part of the primary
lead is produced in the oxidation furnace, and an intermediate slag port is opened
in the hearth of the oxidation furnace to discharge the intermediate slag with
high Cu content. The hearth end of the reduction furnace is also provided with
an intermediate slag port for discharging the intermediate metal layer in the
smelting process.
