A few days ago, Fuping ISF Environmental Science Research Institute invested 50 million yuan, and the annual treatment of 1.5 million tons of red mud project was successful. The project adopts spiral re-election and magnetic separation to extract iron, silicon and aluminum from red mud, which is used to remove red mud. The remaining red mud is added to the coal residue and then extruded to form bricks. This not only realizes that the aluminum ore waste will be eaten dry. "Cleaning" has turned waste into a treasure and succeeded in solving the problem of shelving the red mud and greatly reducing the occupation of land by red mud. The picture shows the worker viewing the iron powder extracted from the red mud.
