Iron ore - Wikipedia
Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from theIron Ore Statistics and Information | U.S. Geological Survey,Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries.IRON ORE1 - USGS,production company.

How iron is made - material, manufacture, making, history,
The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less.White Paper,best grades of iron ore are actually sourced from lower-grade in situ ore bodies. In other words, sometimes the purest iron ore can be made from relatively low-grade ore bodies that then use processing to separate the higher-grade iron ore and generate higher-grade products.
