Fig. 6 Process flow chart of CSC technology applied to lead zinc oxide mine
Fuming volatile bed capacity (T/(M
2 · d)): 70–90
Oxygen enrichment concentration (%): 30–45
Oxygen consumption (m
3 /T): 40–60
Coal consumption (kg/T): 140–180
Melting temperature (°C): 1200–1300
Zinc content grade of secondary zinc oxide (%): 61.61
Total volatilization rate of zinc (%): 97.20
Total volatilization rate of lead (%): 97.44.
(5) Main features
It is the first time to use the process of oxygen-enriched side-blown smelting
and traditional fuming furnace to treat the lead-zinc oxide ore, which realizes
the recovery of valuable metals such as lead-zinc, solves the problems of high
energy consumption, poor environment, short life of kiln lining, non-recovery of
valuable metals such as gold and silver in traditional rotary kiln process [3–5],
and opens up a new technical route for the treatment of lead-zinc oxide ore.
Antimony Smelting
At present, the antimony pyrometallurgy process is the dominant process for antimony smelting, with the most important representative being the “antimony concentrate volatilization and smelting in blast furnace → reduction smelting and refining
