Open-pit mining differs from quarrying (with the possible exception of iron ore) in that the valuable mineral constitutes only a small proportion of the total tonnage of rock produced. In quarrying, the rock itself is the valuable commodity, with virtually all of the raw rock that is won being processed (often only by crushing and screening) to ...Web

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 heavy.Web
