sponge iron process: August 2013 · Hematite is also known as "natural ore". The name refers to the early years of mining, when certain hematite ores contained 66% iron and could be fed directly into iron making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. 98% of the mined iron ore is used to make steel.[1]

Iron ore – Anglo American – Kumba Iron OreHematite is the more soughtafter ore and the preferred raw material in efficient steelmaking mills. It accounts for approximately 95% of South Africa's iron ore production. These iron ore reserves are all of high quality Hematite allowing us to produce both high quality lump (%Fe) and high grade sinter fines (%Fe) for the domestic and export markets.
Iron ore | BHPThere are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red. Iron is responsible for the red colour in many of our rocks and the deep red sands of the Australian deserts.
Iron ore pelletization · In contrast, the GK system has been demonstrated to be capable of producing fired pellets using a variety of pellet feeds, such as magnetite, hematite, specularite, goethite, pyrite cinder, and their mixtures ( Fu and Zhu, 2007 ). The largest annual capacity of GK systems has reached 6–7 Mt.
