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. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.
Iron ore can be extracted through different mining techniques, depending on the depth and accessibility of the ore deposit. The two primary methods of extraction are open-pit mining and …

The grain size of ore fines and concentrates is typically 0–8 and 0–3 mm, respectively.Grains smaller than 0.1 mm are not desired because they reduce the gas permeability of the bed and thus decrease the sintering efficiency.Recycled materials, such as …
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).
The first step in the process is the production of pig iron from which the iron ore is converted in the blast furnace and usually occurs in the form of iron oxides. The heated air is blown into the furnace at the bottom which assist in the coking to be burnt and to produce high temperatures (about 1,500°C).

Iron ore can be mined from all places in the world but to be commercially viable, the percentage of iron in this iron ore needs to be at least 20%. This is because lower iron content in the ore will render all the money and effort exerted in mining the ore from under the surface of the earth a big waste.
