WebAt 900 – 1500 K, In the lower sections of the furnace, C + C O 2 → 2 C O. F e O + C O → F e + C O 2. The limestone also decomposes to CaO which removes the silicate impurity of the ore in the form of Slag. It can be easily separated out of molten iron. The iron manufactured in Blast Furnaces contain about 3 – 4 % of Carbon and smaller ... WebSep 27, 2024 · Among these ores, hematite is the most commonly used one. The extraction of iron from its ore is done in the following ways: 1. Concentration: During this process, the iron ore is crushed into pieces. These crushed pieces are concentrated by gravity separation method in which it is washed with water to remove sand, clay, and dirt. 2.

WebThis method is used to generate limited quantities of oxygen for life support on submarines, aircraft, and spacecraft. Hydrogen and oxygen can be generated by passing an electric current through water and collecting the two gases as they bubble off. Hydrogen forms at the negative terminal and oxygen at the positive terminal. WebSteel-making processes. Steel is made by the Bessemer, Siemens Open Hearth, basic oxygen furnace, electric arc, electric high-frequency and crucible processes. In both the Acid Bessemer and Basic Bessemer (or Thomas) processes molten pig iron is refined by blowing air through it in an egg-shaped vessel, known as a converter, of 15-25 tonnes ...
