What Is Structural Steel and How Is It Created?, · The molten iron is drawn off and is further heated to allow the inclusion of other substances, such as manganese, that deliver different properties to the finished steel product. Once the steel has been created, it is formed into a number of different configurations, depending on how it will be used.How is iron obtained from its ore?, Iron ore consists of the element iron combined with other elements, mostly oxygen. During smelting, the iron ore is heated with carbon. The carbon combines with the oxygen and carries it away, leaving iron. Carbon was originally obtained from charcoal derived ...Environmental impact of iron ore mining, Introduction Iron ore Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined.
