Mining of iron ore can be manual or it can be mechanized depending upon the size of the mine and the reserves of iron ore to be extracted. The taconite powder with the iron in it is called concentrate. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties. Iron ore was the third-highest-value metal mined in the United States, after gold and copper. Mar 14, 2014018332Large iron ore mines are mechanized mines while manual mining methods are employed in the small mines. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Net exports (exports minus imports) were 3.9 million tons. This iron could be given different shapes to make weapons and tools. Hematite is an iron oxide mineral. The iron ore is separated from the taconite using magnetism. To be economically viable for mining, iron ore must contain at least 20% iron. It is also one of the oldest metals and was first fashioned into useful and ornamental objects at least 3,500 years ago. Nearly every construction of man contains at least a little iron. Almost all (98%) iron ore is used in steelmaking. Although some of the iron mined by CVRD in the 1950s and 1960s went to domestic steel mills, much of it was exported to foreign markets. Mechanized mining involves creation of benches that are used for the purpose of drilling, blasting, and finally the transportation of the iron ore to the crushing plant.
