Analysis for Molybdenum Concentrate Carbon-free Roasting Process AITranslate
Abstract AITranslate
Thermal balance was tested of traditional roasting rotary furnaces of molybdenum concentrate, and its roasting process was analyzed. It is pointed out that MoS2 roasting can take place based on self-heat- ing under the industrial-scale production conditions, and proper cooling measures should be adopted to pre- vent overheating. Therefore, carbon-free roasting technology of molybdenum concentrate was developed, and thermal balance tests and technical analysis of the corresponding rotary furnace were carried out. The results show that outer heat source used in traditional roasting no longer appears in carbon-free roasting, because roasting heat is enough to ensure spontaneous occurrence of the reaction. In fact,heating is needed just at the beginning of the reaction to make molybdenum concentrate on fire and after violent reaction to remove residual sulphur, without additional heating during operation. The above technology has obvious advantages in saving energy and emission reduction, improving yield and quality of molybdenum calcine, re- ducing heat loss, and increasing SO2 concentration of flue gas.
