Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe 3 O 4 ), hematite (Fe 2 O 3 ), goethite (FeO(OH)), limonite (FeO(OH)183;n(H 2 O)) or siderite (FeCO 3 ).

Iron Production Was A Closely Guarded Secret in Ancient TimesOpen Pit Mining Is Used For The Production of Iron OreBenches Are Made For The Process of Iron Ore MiningMankind has known about the existence of iron in its ores for thousands of years. In ancient times, iron ore was heated inside an oven with wood so that it melted and left behind slag that contained iron. This slag was repeatedly hammered and heated to extract iron. This iron could be given different shapes to make weapons and tools. However, before the rock containing iron can be smelted in a blast furnace, it has to be extracted or mined from inside the surface of the earth. Iron ore miningChat Online

Different Types of Iron Ore Mineral Processing amp; Metallurgy
Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.
Open pit mining, also known as opencast mining, open cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.

Iron Ore Pelletizing Process An Overview IntechOpen
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process

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 dont need beneficiated, fines which are generated can be pelletized and used instead of being disposed of.
