Co-utilization of iron ore tailings and coal fly ash for porous
Iron ore tailings (IOTs) are an inevitable by-product produced during the beneficiation process of iron ore (Almeida et al., 2023). The rapid growth of mineral mining and ferrous metallurgy has led to an increase in the generation of IOTs. Approximately 0.40–0.60 tons of IOTs are generated in the treatment of 1.0 ton of iron ore.

Beneficiation of low-grade, goethite-rich iron ore using …
As high-grade iron ore deposits are gradually being depleted, more difficult-to-process ores such as goethite-rich, low-grade iron ores and tailings are now being processed. These ores often contain impurities and require some form of beneficiation in order to achieve the typical grades required for sale to downstream steel producers.
