     · was won by drilling and blasting .As mining technology generally developed, so did drilling techniques and the explosives used. Smith 1990 reported that the Cleveland deposit was associated with a very strong stone roof rock known as “dogger” allowing mine drivages to be self-supporting. However, he states that in later years where the mining had progressed to the dip, this

  • Iron Extraction Process - Dillinger

    At the bottom of the furnace the iron ore is chemically reduced. The blast reacts with the coke carbon dioxide and carbon monoxide are formed at temperatures of up to 2000 °C. The carbon monoxide removes the oxygen from the iron ore resulting in pig iron production. Slag is formed from the other ore components and the additions. Casting bay

  • Iron ore

    Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite Fe 3O 4, 72.4% Fe, hematite Fe 2O 3, 69.9% Fe, goethite FeOOH, 62.9% Fe, limonite FeOOH·nH2O, 55% Fe or siderite FeCO3, 48.2% Fe. Ores containing very high quantities of hematite or magnetite greater than about 60% iron are known
