Iron processing Iron processing Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.

learn moreIronmaking Process an overview | ScienceDirect Topics
· For example, for the ironmaking process, iron ore (sinter or pellet), coke, coal, and air blast are charged separately, but inside the BF they are mixed together, and reactions occur, such as combustion, heatingup, carbon solution loss, ore reduction, decarburization, and desulfurization of molten iron. Finally, the hot metal and molten slag are formed and tapped out periodically.

In 1879 Sidney Gilchrist Thomas and Percy Gilchrist adapted the Bessemer converter for use with phosphoric pig iron; as a result, the basic Bessemer, or Thomas, process was widely adopted on the continent of Europe, where highphosphorus iron ores were abundant. For about 100 years, the openhearth and Bessemerbased processes were jointly responsible for most of the steel that was made,

Process. Direct reduction processes can be divided roughly into two categories: gasbased, and coalbased. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
