| Abstract: |
| The reduction of lead-rich slag from oxidation bottom blowing furnace was conducted by adding coal. The effects of ratio of coal to lead-rich slag, reduction time and temperature, and ratio of CaO/SiO2 and Fe/SiO2 on reduction were studied. The lead content in slag is below 2% and zinc content in slag is above 85% under the optimum conditions including coal ratio of 3.25%~3.50% at reduction temperature of 1 225 ℃ for 30 min. |
