| Abstract | The invention relates to the technical field of molybdenum disulfide and in particular relates to a comprehensive utilization method for preparing molybdenum disulfide from waste molybdenum slag. Themethod comprises the following steps: drying waste molybdenum slag, and roasting the dried waste molybdenum slag in the presence of an inert gas; reducing the temperature after roasting, and discharging so as to obtain a crude product of molybdenum disulfide; grinding the crude product of the molybdenum disulfide, carrying out acid soaking, namely carrying out acid soaking with hydrochloric acid and hydrofluoric acid in sequence, and carrying out aftertreatment after acid soaking, thereby obtaining molybdenum disulfide. By adopting the method provided by the invention, wastes can be effectively utilized, resources can be saved, the environment can be protected, the cost can be reduced, and the economical benefits can be increased.
本发明涉及二硫化钼制备技术领域，特别是涉及种废钼渣制备二硫化钼的综合利用方法。该方法包括以下步骤：将废钼渣干燥，干燥后的废钼渣在惰性气体保护下进行焙烧；焙烧后降温出料得 |
