Composition: Iron ore is primarily composed of iron, usually in the form of iron oxides such as hematite (Fe2O3), magnetite (Fe3O4), or goethite (FeO(OH)). It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements.; Physical properties: Iron ore is usually hard, dense, and …
Details
It's important to note that goethite is often present alongside other iron oxide minerals, such as hematite and magnetite, in iron ore deposits. The specific distribution and mining of goethite can vary based on the geological characteristics of each region and the nature of the iron ore deposits present.
