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 preconcentration followed by direct reduction and magnetic separation. Then, slagtailing concrete composite admixtures were prepared from highsilica residues.

In Table 2, it can be seen that the highest negative effect on RDI + is exhibited by the interaction of iron and silica followed by the individual effect of iron. On the other hand, silica exhibited a positive effect on RDI + of the reduced manganese ores. The results in Table 3 indie that both of iron and silica have an individual positive effect on RDI + while the interaction ...
Developments in the physiochemical separation of The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores
