How Is The Iron Ore Mined? - FTM Machinery

Iron ore is an important raw material for steel producers. Natural iron ore is gradually selected from iron by means of crushing, grinding, magnetic separation, flotation, re-election, etc. Iron ore is a mineral aggregate that can be economically utilized with iron or iron compounds. Any ore containing iron that can be used economically is called iron ore. There are many kinds of iron minerals, and about 300 kinds of iron minerals and iron

The history of iron ore prices differs significantly from other metals. For most of its history the price of iron ore has been fixed globally, and for very long periods. Since the beginning of global pricing, which is pre-1900, the price has remained relatively fixed up until 2003. In that ~100 year period the price changed only once, from A$2/tonne to A$9/tonne in 1965. Since 2003 the iron ore price has fluctuated,
