A Life Cycle Assessment study of iron ore mining ...
This stone assessed the cradle-to-gate life cycle of an iron ore mining. The study was based on production data from an open pit mine located in the Iron Quadrangle/Brazil. The functional unit was defined as “one tonne of iron ore concentrate produced” and the data used were collected directly from the companys production reports covering the time of one year.

Iron Ore - an overview | ScienceDirect Topics
Iron ore is used directly in the steelmaking process in the blast furnace in the form of lump, pellet, and fines (see Fig. 5). (Fines are converted to sinter feed in a sinter plant.) Iron ore pellets are also used in the production of DRI and HBI.

Iron ore - Wikipedia
This stockpile of iron ore pellets will be used in steel production. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe
