Extensive development of low grade ores and open pit mining began after World War 11, and a relatively new process, agglomeration, then began to yield an iron ore concentrate that contained about sixty-five per cent iron compared with fifty-six to sixty per cent from the average underground workings of the high grade ore.
In 1845, the search for iron ore began in earnest, and the first major discovery was made near the present site of Negaunee. The men of the search party formed the Jackson Mining Company on July 23, 1845, and iron mining in Michigan officially began.
How is iron extracted from its ore? Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.
Sep 18, 2020 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).
World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
