Abstract

PURPOSE: To efficiently recover a valuable metal and a harmful metal, by using a mixture of coke and coal as a reducing agent for reduction of duct, effecting high- temperature reduction and continuously measuring the temperature of an atmosphere to control the distribution of the temperature to be appropriate.
CONSTITUTION: Dust collected from an electric furnace is made into pellets. The pellets are charged into a rotary kiln 1 together with a reducing agent which is prepared by mixing 100pts.wt. of coke with 20W100pts.wt. of coal. The pellets are moved in the kiln 1 so that the pellets are reduced at 1,200W1,400°C in the sequence of iron, zinc, lead, etc. At that time, early reduced iron is oxidized again in a high- temperature region. The reduction of the zinc, lead, etc. is accelerated by the heat of the oxidation. Evaporated zinc lead, etc. change into oxides, which go out of a furnace end hood 3 and are collected by a cyclone 8 and a dust collector 9. Exhaust gas is released through a chimney 11. Thermometers T1WT5 are installed in the kiln 1 to continuously measure the temperature of the atmosphere. The pressure in the furnace, the oil combustion in a burner 5, the mixture ratio and addition ratio of the reducing agent, etc. are controlled depending on the difference between the measured temperature and a standard value to keep the temperature of the atmosphere in the kiln appropriate.
