Iron ore tailings, which are important secondary resources, have outstanding latent application value in iron recovery. In this study, a pilot-scale experiment on the iron recovery from iron ore tailings was investigated using innovative technology of pre-concentration and suspension magnetization roasting (SMR), followed by magnetic separation and flotation.

Based on the ore characteristics (e.g. particle size, mineralogy and grade), gravity concentration (jig and Humphreys spiral), magnetic separation (low and high-field) and inverse cationic flotation (especially applied to pellet feeds) are used [3], [4]. It is estimated that for each tonne of beneficiated iron ore, 400 kg of tailings are produced.

Typically, mill tailings range from sand to silt-clay in particle size. Ore is material that contains a mineral commodity of value required to sustain modern life. Mineral commodities commonly recovered in the United States are copper, gold, silver, iron, lead, zinc, uranium and coal.

recover most of the iron values lost at present from the washery tailings. The high grade iron ore fines can be used in the sinter feed to some extent without affecting the sinter qualities using suitable sintering techniques. In order to get the raw material at lower cost the utility of super grade iron fine concentr-

Recovering Iron from Iron Ore Tailings and Preparing . Iron ore tailings (IOTs) are a form of solid waste produced during the beneficiation process of iron ore concentrate. In this paper, iron recovery from IOTs was studied at different points during a process involving pre-concentration followed by direct reduction and magnetic separation.

Therefore, the recovery and utilization of iron in iron ore tailings are very important to save iron resources. At present, magnetizing roasting and direct reduction are the two main ways to recycle iron from tailings or other iron contained wastes [12]. The differences between them are summarized in Table 1. Table 1.
