[0003] In the process of dry iron ore concentrate extraction, most of them adopt a single air separation or magnetic separation method to extract the iron ore concentrate. However, the iron ore concentrate is not fully extracted, and the air separation method will generate dust and pollute the environment. Therefore, the present application proposes an iron ore concentrate extractor with effective dust prevention. Utility Model Content
