FLUIDIZED-BED ROASTING OF MOLYBDENITE CONCENTRATES

摘要

The present invention is directed to a fluidized bed roasting apparatus and method for converting molybdenite to molybdeum trioxide. The fluidized bed roasting apparatus includes cooling tubes, a means of vibration, a distributor plate, fluidizing gas preheaters, and an expanded upper section. The apparatus can be continuously operated using an automated control system.
