    Hydraulic mining uses water power to fracture and transport a bench of Earth or gravel for further processing. Hydraulic mining is used for placer deposits of gold, tin, and other metals. Surface mining equipment is similar to construction equipment (e.g., scrapers, bulldozers, drills, shovels, front-end loaders, trucks, cranes, draglines).

  • History of the Iron Ore Trade : The Cleveland Memory Project

    The balance of the ore was used in Wick's rolling mill at Youngstown, Ohio for the same purpose. In both cases, the ore was found to be quite satisfactory. It was not until 1853 that the iron companies concluded that the attempt to make iron in the upper peninsula was futile. They then took up the shipping of the iron ore to the lower lakes.

  • How Is Iron Extracted From the Earth? - Reference.com

    Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

  • mining - Underground mining | Britannica

    mining - mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on …

  • iron processing | Britannica

    When iron making was properly established, two types of furnace came into use. Bowl furnaces were constructed by digging a small hole in the ground and arranging for air from a bellows to be introduced through a pipe or tuyere. Stone-built shaft furnaces, on the other hand, relied on natural draft, although they too sometimes used tuyeres.

  • Up Close: Iron Mining in the Upper Peninsula | WXPR

    Michigan's Upper Peninsula is home to a pair of open pit iron mines that have been operating for several decades. Standing on the edge of Empire Mine is like looking into an amphitheater far too big for any performance. It's a mile wide and a mile across. 1200 feet deep. I start wondering how many swimming pools it would take to fill it.
