Shale Wikipedia

Shale is a fine-grained, clastic sedimentary rock, formed from mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by its tendency to split into thin layers less than one centimeter in thickness.This property is called fissility. Shale is the most common sedimentary rock.

Iron mining in the United States Wikipedia

Iron mining in the United States produced 48 million metric tons of iron ore in 2019. Iron ore was the third-highest-value metal mined in the United States, after gold and copper. Iron ore was mined from nine active mines and three reclamation operations in Michigan, Minnesota, and Utah.Most of the iron ore was mined in northern Minnesota's Mesabi Range.

The pre-mining watertable of the BS2 orebody was approximately 618 mRL. Bores screened in the areas north of the BS2 within the Mt McRae Shale and Nammuldi valley have groundwater levels at 576 to 580 mRL. Dewatering of the mining area to allow access to the ore would lower the groundwater table of the orebody aquifer to approximately 520 mRL.

Virginia Geological Survey Civil War Iron

Iron occurs as a variety of minerals across the state of Virginia, but mining operations prior to the Civil War exclusively used a type of ore known as limonite. Limonite is a hydrated iron oxide with a general formula FeO(OH)nH2O, commonly a byproduct of the weathering of iron-rich sulfide or silicate minerals.

Jan 10, 2017  In most BIF-based iron ore mines, iron was enriched either by: i)supergene enrichment processes typically resulting in “martite-goethite ore” with 60–63 wt.% Fe; or ii)by hypogene hydrothermal processes forming “high-grade haematite ore”, with 60–68 wt.% Fe. Martite is a term that denotes haematite pseudomorphs replacing magnetite.

Iron ore Wikipedia

Mining iron ore is a high-volume, low-margin business, as the value of iron is significantly lower than base metals. It is highly capital intensive, and requires significant investment in infrastructure such as rail in order to transport the ore from the mine to a freight ship. For these reasons, iron ore production is concentrated in the hands
