| effective way to mine iron ore.Iron is the | | | | |
| cheapest and most common metal available for | | | | the world.In 1844, government surveyors |
| | | | found a large iron ore deposit of |
| mining. Iron is used for making steel. | | | | |

| is very dependent | | | | iron ore around Lake Superior and the |

| he would have earned billions of dollars in | | | | |

| Iron is brittle and cannot be used to | | | | |
| manufacture any products because of this | | | | to produce large quantities of steel. Some |
