| Abstract: |
| Based on the theoretical study of roasting mechanism of molybdenum concentrate and the roasting practice of molybdenum concentrate in multi-hearth furnace, the high temperature waste gas was imported into multi-hearth furnace as the supplement heat source for the molybdenum concentrate roasting. The temperature within the hearths furnace can be maintained at the optimum range of 550~650 ℃. The carbon-free roasting technology is successfully developed. |
