Some iron tailings' disadvantages pose challenges in their reuse processes as backfill materials, especially for superfine tailings. With the development of ball-milling and magnetic separation technologies for ore treatment, the resulting iron tailings become very fine, even with the 5–75 μm size (Quast and Skinner, 2020).These superfine tailings will increase …
