WitrynaMaking steel. Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route. Both processes are being … WitrynaIMPROVED STEEL MAKING PROCEDURES. Social Darwinism The application of ideas about evolution and "survival of the fittest" to human societies - particularly as a …
