  • 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. Then, slag tailing concrete composite admixtures were prepared from high silica residues.

    History . Iron was likely originally discovered and extracted as a result of wood burning on top of iron containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present day Iraq) between 2700 and 3000 BCE.
