Brief History of High-Grade Iron Ore Mining in North ...

The transformation of many hypogene iron orebodies of reasonable grade and size to the giant deposits exploited today can be related to this geologically recent supergene overprint; most of the past and still much of the present mining of high-grade iron ore relates to soft ore interpreted in most cases to be the direct result of supergene processes. Also mentioned here should be the recent ...

Mesabi Range - Wikipedia

Iron ore was discovered north of Mountain Iron, Minnesota on 16 Nov. 1890 by J.A. Nichols of the Merritt brothers. The range was defined by 1900. Initially underground mines were employed but these gave way to open pits so that by 1902, half the operations were conducted this way. The last underground mine closed in 1960. Natural ores eventually gave way to iron-ore concentrates from

North Pennines - Northern Mine Research Society

The North Pennine fluorspar zone is centred on Weardale and during the 19th century the area supported a number of mines working this mineral, with lead ore as very much a by-product. This industry died out in the 1980s as world prices fell and the national steel industry was reduced in preparation for privatisation.

Rosedale Mines and Tramway – Subterranea Britannica

At Bank Top the inclined tramway from Hollins Mines (SE729945) transported the iron ore up around 400ft to the large kilns just below the N.E.R. branch terminus. The ore was tipped into the kilns from above to be ‘roasted’ to drive off water and carbonic acid gas. This process is known as calcinations and dramatically reduces the weight of the ironstone which in turn reduces transport ...

Roseberry Ironstone Mine - North York Moors

Reopened in 1907, the mine initially prospered, becoming the largest of the three ironstone mines in the Roseberry area. In 1917 it produced 203,594 tons of ore for the blast furnaces of Teesside and by 1919 employed a workforce of 386. However, the global recession of the 1920s brought a slump in iron prices and the mine closed again in 1924, before being abandoned a few years later.
