The emerging alternative ironmaking technologies—direct reduction and smelting reduction—are only briefly introduced, and will be described in a separate chapter in this book series. In the beginning, there is a short introduction to the ironmaking history followed by a general description of the blast furnace ironmaking process, and its role in the global steelmaking industry.

Baking powder is a dry chemical leavening agent, a mixture of a carbonate or bicarbonate and a weak acid. The base and acid are prevented from reacting prematurely by the inclusion of a buffer such as cornstarch. Baking powder is used to increase the volume and lighten the texture of baked goods. It works by releasing carbon dioxide gas into a

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other
Aluminum is the most abundant metal in the earth’s crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes. Bauxite is the general name given to the hydrated oxides of aluminum. It contains varying amounts of

When we say that gold is 24 carats, what does it mean? It means that the gold is completely absent from impurities, it is entirely pure. Now, this does not happen naturally. Metals extracted or mined always have some impurities in them. The process of removing such impurities is known as refining. Let us learn more.
