The first shipment of ore in any quantity consisted of 152 tons, which was sent by the Cleveland Iron Mining Company to the Sharon Iron Company in Sharon, Pennsylvania in September, 1853. It took four vessels to move the ore from Marquette to Sault Ste. Marie, Michigan, where it was portaged over the falls to be reloaded on another vessel.

As it turned out, the iron would become more valuable to northern Minnesota than the gold. Iron ore was discovered on the three iron ranges at different times. The first ore shipped from the Vermilion Range was in 1884, the Mesabi Range in 1892, and the Cuyuna Range in 1911. The mines were operated through the hard work of the miners.

The author has lived most of his life in close proximity to the iron works and the mines, has visited other early iron works, and has done much research on the subject. Much of the information used above has been taken from an unpublished 13 page report by James Garvin, "Chronology of the Development of the New Hampshire Iron Factory Company ...

State mineral data - After all information from the USGS annual canvass of domestic mineral industries is compiled and the mineral commodity chapters (Volume I of the Minerals Yearbook) are released, a Statistical Summary chapter is completed, with table 5 (and several other tables) presenting the earliest State-by-State data, including total State production and production

Mining of coal and metallic minerals in Washington began in the mid to late 1800s. Coal production in Washington hit a high in 2003 with an estimated total production of 6,232,000 short tons, yet production ceased in 2006. Metals mining during the same general time period occurred on both sides of the Cascade divide, but was largely concentrated in the northeastern portion of

Iron "ore" used for the manufacture of Portland cement does not need either the grade or the color used for pigment manufacture. If the Iron Chancellor Mine were to become an iron source for the new Drake Cement plant, mining would likely be from a newly developed open pit. The high grade, red hematite

The next mines that started in the following years were The "Cleveland" and "Lake Superior Mine", Located in Ishpeming. With more and more mine starting in the area, the "Iron Cliffs Mining Company" started the "Barnum" mine in 1867, just north of the "Lake Superior" Mines This mine operated very successfully for many years.

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property. Mines By State Over 110,000 mines from the USGS MRDS database have been categorized by state. Alaska Mines

The mining industry is steadily moving toward a future where it's possible to virtually construct and deconstruct buildings, plants, mines, and all associated infrastructure before even breaking ground to create a truly intelligent mine. 2. Geographic information systems

Iron ore of Dalli-Rajhara located in the central parts of the range are captive mines of Bhilai Steel Plant (BSP). Recently an iron ore bearing area is discovered in Kabirdham district and known as Eklama iron ore complex. This area is expected to yield high-grade hematitic iron ore in substantial quantity and support iron & steel units.

Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). These iron ores have been mined to produce almost every iron and ...

Earth's crust contains many minerals and other materials that are useful to people. To get these valuable natural resources, people must dig into the ground. The holes that they dig are called mines. Some mines are narrow shafts, or tunnels, that go very deep underground. Other mines are large open pits, like canyons. The people who work in ...

Mineral Mining and Processing Effluent Guidelines. EPA promulgated the Mineral Mining and Processing Effluent Guidelines and Standards ( 40 CFR Part 436) in 1975, and amended the regulation in 1976, 1977, 1978, and 1979. The regulation covers wastewater discharges from mine drainage, mineral processing operations and stormwater runoff.

Iron Ore Statistics and Information. Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel ...

In the early twentieth century iron mining became less and less important in Tennessee as the number of producing mines and the volume of ore production both dropped by roughly half from 1909 to 1919. Iron's close companion in early industry was coal. Tennesseans began to mine coal in small quantities during the 1840s.

The BFS envisaged a 100Mtpa integrated iron ore mining operation over an estimated mine life of 40 years. The proposed project involved the development of two open-pits, the Ouéléba pit (53Mtpa) and Pic de Fon pit (47Mtpa) at Simandou South, and the construction of a 630km railway and a port, for a total investment of £13.6bn ($20bn).
