Read More4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, low-capacity mines have rapidly disappeared.
Read MoreIron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH)n(H2O)) or siderite (FeCO3). Roughly 98% of iron ore on the global market is used in iron and steel production. Common methods of extracting the iron ore consist of blasting, drilling, or general excavating, Most iro

Iron ore is a type of mineral and rock from which metallic iron is extracted economically. This ore is normally rich in iron oxides and vary in color from dark grey, bright yellow and deep purple to rusty red.
Read MoreJan 01, 2015 Iron ore 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 ...
