Ore mine gangues which are industrial wastes can act as potential sources of industrial materials. Typical iron ore minerals may contain antimony, arsenic, beryllium, cadmium, chromium, copper, lead, nickel, as well as silver and zinc [6]. The economic viability of these metals would depend on their various amounts in the iron ore.

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.
