Iron ore is an important raw material for iron and steel production enterprises. After crushing, grinding, magnetic separation, gravity concentration etc, gradually we can get iron from natural minerals iron ore. It is the mineral aggregates that contain iron or iron compounds which can be used economically. Production Process of Iron Ore Generally, the processing of iron ore needs several processing

Iron mining process. 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 nations steel. blasting. taconite is a very hard rock. using explosives, the taconite is blasted into small pieces. transportation.
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. the first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.
Haematite and magnetite are the most commonly found iron ore minerals. the smelting process allows the iron ore to be heated with carbon. the carbon combines with the oxygen and carries it away, leaving behind iron. blast furnaces are so hot which is why they melt the iron, and drain it off to be poured into moulds to form bars, called ingots.
Fine ore and ore powder, on the other hand, are specially processed for the blast furnace process. this ore processing will be discussed in more detail in the next section. iron ore processing. after the iron ore has been prepared by crushing and grinding during ore extraction, the ore is actually processed.
Mining and processing of iron ore involves coarse crushing and screening. iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening. this is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse.
Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter. here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron.

World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. the only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. sinter is the primary feed material for making iron and steel in a blast furnace.
By the mid-1800s there were iron mines operating in dodge and sauk counties, and by the turn of the century, iron was being mined in jackson, florence, marinette, iron and ashland counties. much of this early iron mining occurred in small, underground mines and was a major contributor to the cultural identity of these areas that still resonates ...

The worlds resources are dominated by low-grade ore, though current world production of iron ore is largely by supply from deposits of high-grade ore composed of either rocks of massive hematite or pisolitic goethite. world iron ore production in 2013 was 2.95 billion tonne, with the major producers being china, australia, and brazil.
