How is Iron Ore Mined Pediaa.Com

Iron ore can be mined from all places in the world but to be commercially viable, the percentage of iron in this iron ore needs to be at least 20%. This is because lower iron content in the ore will render all the money and effort exerted in mining the ore from under the surface of the earth a big waste. This is why minerals near the surface of the earth and containing as a high percentage of iron are mined for the production of iron. Most of the iron ore produced in the world is extracted from the earth’s crust through

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-containing minerals have been discovered, among which more than 170 kinds ar
