Iron Making Boundless World History

Small groups of part-time miners used shovels and primitive equipment. As a result of these limited methods, in the deep Tyneside pits (300 to 1,000 ft deep) for example, only about 40 percent of the coal could be extracted. Coal was so abundant in Britain that the supply could be increased to meet the rapidly rising demand. In 1700, the annual output of coal was just under 3 million tons ...

Iron Ore - Mining Artifacts

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. 98% of the mined iron ore is used to make steel. Minnesota's iron ore was actually discovered while prospectors were searching for gold. Since the object of their search was gold, the iron was ignored. It turned out the iron would become much more valuable to northern Minnesota than the ...

10/10/2017  A specialized type of coal, called hard coal, is used to make coke, a porous form of carbon. Coke is a reductant or a chemical that can reduce iron oxide to iron metal – especially when combined with heat and oxygen. Hard coal has high-carbon content and low ash, sulfur and phosphorus levels. Coke is made in a coking oven by heating hard coal in the absence of air or oxygen. The iron ore can ...

The HIsarna steelmaking process is a process of primary steelmaking in which iron ore is processed almost directly into steel. The process is based on a new type of blast furnace called a Cyclone Converter Furnace, which makes it possible to skip the process of manufacturing pig iron pellets, a necessary step in the basic oxygen steelmaking process. Because it skips this step, the HIsarna ...
