Low-grade martite type ores: are mainly distributed in the 6th iron ore layer. Martites of the ores are steel gray in color, and show striped and massive structures. The metallic minerals are specularite, martite and a small amount of magnetite and limonite; the non-metallic minerals are mainly quartz, and then followed by amphibole minerals.

Iron Ore Origins. Deposits that contain metals in economically exploitable quantities are known as ores. When metallic elements are found in nature in solid inorganic compounds, they are called minerals. The most common iron-containing ore is haematite (Fe 2 O 3), but iron is widely distributed in other minerals, such as magnetite (Fe 3 O 4).

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.

Theoretically, the highest iron content in iron ore is around 72%, and iron ore with an iron content above 60% is called rich iron ore. Iron ore is first reduced to iron (pig iron) in a furnace, then sent to a steel-making furnace for decarburization and refined into steel. Scrap steel can also be melted and regenerated in a steel-making furnace.
