Mining technology consists of the tools, methods, and knowledge used to locate, extract, and process mineral and metal deposits in the earth. The methods used to locate ore bodies range from on-the-ground reconnaissance by prospectors to remote sensing techniques such as satellite imagery.
what materials are used in mining iron. Apr 24 2017 · Raw Materials These combinations are known as iron oxides Mining pulls most of the iron from iron ores which are rocks found on the outer layers of the earth that contain iron This iron ore is then converted into various types of iron but first it is processed in a blast furnace to produce pig iron. Details
Apr 15, 2012· However, mining is not the only supplier of these raw materials. Next to the primary mining industry a secondary mining industry is growing: 'urban mining'. The existing stock of materials in the urban environment is recycled more and more. 38% of iron input in the steel making process comes from scrap.

Specialised underground mining equipment such as diggers, loaders, and trucks are used to excavate raw materials and transferred to the surface with lifts for future processing.
From blasting to crushing to separation – more than 85% of the iron mined in the United States is mined in northeastern Minnesota to make our nation's steel. Blasting Taconite is a very hard rock. Using explosives, the taconite is blasted into small pieces. Transportation The taconite pieces are scooped up by electric shovels. Each...
Blood cells rich in iron carry oxygen from the lungs to all parts of the body. Lack of iron also lowers a person's resistance to infection. It is estimated that world wide range of 800 billion tons of iron ore resources, containing more than 230 billion tons of iron. Iron ore is the raw material used to make pig iron.
Mar 14, 2014· The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH).n(H2O)) or siderite (FeCO3). The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps.
