Iron Mining Process. From blasting to crushing to separation more than 85% of the iron mined in the United States is mined in northeastern Minnesota to make our nation’s steel. Blasting Taconite is a very hard rock. Using explosives, the taconite is blasted into small pieces. The iron ore is separated from the taconite using magnetismget price

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 get price

Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface area for reactions. Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed ore.get price
