· How Is Iron Extracted From the Earth? Reference. Iron ores in the form of hematite ferrous oxide and magnetite are removed from the earth through mining The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or .
Concentration: The ore is then finely ground and further purified, to remove silicon, sodium, potassium, phosphorus, apatite etc. Additives like olivine, quartzite, limestone and dolomite are then mixed into the resulting slurry (a mix of ground iron ore and water).
· The formation of iron ore is attributed to geological processes of crystallization from silie solution. Denser ferrous materials precipitated to the base of the ocean which resulted in the formation of a final rock mass restricted to certain areas that iron rich than others.

Mining iron ore typically involves finding a fertile site, drilling and blasting the ore, and then transporting it to the primary crusher for processing. Crushed ore is sorted over screens and resized to different specifiions (lump and refined products). After the processing, a stacker builds a stockpile in the stockyards.
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.
Iron ore reserves are normally found within a few meters from the ground surface, and most of the major mines of the world are operating an opencut system, which requires little sophistiion, except in terms of the equipment used and the quantities needed to be mined for operations to be costeffective.
