The iron ore tailing sample was a granular high-silicon solid waste obtained after the beneficiation process of iron ore following the steps of stage grinding–gravity separation–magnetic separation–anion reverse flotation. The sample had a size distribution ranging from 0.42 to 831.76 µm.
There are two types of iron resources such as primary iron ore and iron sand. In general, primary iron ores use as raw materials in iron and steel making because the iron content is high (± 60%) and can reduce directly. On the other and, iron sand is rarely used as a raw material because the iron content is low (20-40%) but the iron sand reserves are very …
