Method for producing high-quality industrial molybdenum oxide through air draft self-heating roasting

The invention relates to a method for producing high-quality industrial molybdenum oxide through air draft self-heating roasting. Belongs to the technical field of molybdenum chemical and molybdenum metallurgical furnace burden production and preparation. The preparation method comprises the following steps: by taking molybdenite concentrate as a main raw material, adding a proper amount of kaolin, water and solid fuel, mixing, granulating, distributing on a porous setter plate, igniting, performing air draft self-heating roasting, and collecting dust, thereby obtaining the high-quality industrial molybdenum oxide with the molybdenum content of more than 60wt%. The method has the advantages of low energy consumption, high efficiency, large productivity, good product quality and the like, and is suitable for industrial application. 本发明涉及一种抽风自热焙烧生产优质工业氧化钼的方法；属于钼化工品与钼冶金炉料生产制备技术领域。本发明以辉钼精矿为主要原料，添加适量高岭土、水、固体燃料后混合制粒，布料至多孔承烧板上，经点火、抽风自热焙烧、收尘，得到钼含量大于60wt％的优质工业氧化钼。本方法具有能耗低、效率高、产能大、产品质量好等优势，适宜工业化应用。
