| Abstract: | Based on the theoretical analysis, an experimental study was carried out for the vacuum carbonthermal reduction of lead in the zinc leaching residue. By adding 18.5 g semi-coke powder with 73% fixed carbon content into 100 g zinc leaching residue, the vacuum carbonthermal reduction process with an initial vacuum degree of 10 Pa proceeded at the temperature of 1000 ℃ by holding 30 min, resulting in the reduction rate of lead from leaching residue up to 98.93%. |
