Environmental impact of iron ore mining - Wikipedia

Introduction Iron ore. Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH)n(H 2 O)) or siderite (FeCO 3).Roughly 98% of iron ore on the global market is ...

Open Pit Mining - an overview ScienceDirect Topics

There are two principle types of surface mining, strip mining and open-pit mining (see Fig. 8.8). Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock. Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface.
