Most of the iron mines in Minnesota were close to Lake Superior, less than one hundred miles away. Train would take the ore to docks to be loaded on ships. They then used the mined iron to make railroads, buildings like skyscrapers, cars, bridges, and many other things. The ore itself was found in Minnesota by a geologist in 1865.

When the iron ore is extracted from the mine, it must undergo several processing stages. Six steps to process iron ore 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage.

The very fine iron ore product is obtained after the flotation process. In order to be used in the steelmaking process, it should be pelletized. At smaller percentages, it can also be blended into sinter feed and used at sintering units. The iron content of the CSN Mining pellet feed usually exceeds 66%.

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.

At the processing plant, the taconite is crushed into very small pieces by rock crushing machines. The crushers keep crushing the rock until it is the size of a marble. The rock is mixed with water and ground in rotating mills until it is as fine as powder. Separation The iron ore is separated from the taconite using magnetism.

Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice. This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and

In Minas Gerais, in some mines, the average content is 40% Fe. By the conventional method, the ore is concentrated by means of processing with water to increase the iron content, with most of the tailings deposited in dams or pits. This is where another technology under implementation at Vale stands out: FDMS (Fines Dry Magnetic Separation).

MINING AND PROCESSING: 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. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.

This means that the mined iron ores need to be specially processed in advance before the blast furnace process. Regions in which iron ore has formed over millions of years (e.g. through volcanism) and can be mined economically are also referred to as iron ore deposits. Especially many ore deposits can be found in countries such as China

Bog iron is much easier to smelt because it contains fewer impurities than iron ore in rock deposits, but the quantity of iron available from bog iron is relatively low (although actually renewable, unlike mines; a bog can be harvested for iron again after a few decades as the processes which produce the bog iron continue).

Iron ore was the third-highest-value metal mined in the United States, after gold and copper. Iron ore was mined from nine active mines and three reclamation operations in Michigan, Minnesota, and Utah. Most of the iron ore was mined in northern Minnesota''s Mesabi Range. Net exports (exports minus imports) were 3.9 million tons.

Iron ore can be upgraded to a higher iron ore content through beneficiation This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don’t need beneficiated, fines which are generated can be pelletized and used instead of being disposed of.
