Define Iron Extraction by Blast Furnace Metallurgy?
Iron extraction by Blast Furnace Metallurgy is a process of obtaining iron from its ore. The Blast Furnace is a large steel structure in which the iron ore is heated until it becomes molten. The molten iron is then poured into molds called pigs and hogs which are made of refractory materials. These molds cool and solidify, and the pigs and hogs are then transported to a steel mill where they are used to produce steel.
What is the Procedure of Extraction of Iron From its Ore?
The process of extracting iron from its ore involves a series of steps that begins with crushing the raw ore to extract the iron mineral content. The iron minerals are then separated from the rest of the ore by washing and magnetic separation. The iron minerals are then roasted to produce a high-quality iron oxide that can be further processed to produce pure iron.
What is Calcination?
In chemistry, calcination is the process of heating a substance to a high temperature in air or oxygen. In the process, the substance loses water and carbon dioxide. The product is called a calx.
What is Roasting?
Roasting is a cooking method that uses dry heat, usually in an oven, to cook food. The most common roasting method is to place food on a wire rack above a pan of hot water or oil. The food is then cooked by the hot air that circulates around it.
What are the Differences between Calcination and Roasting?
The main difference between calcination and roasting is that calcination is a thermal treatment that is used to produce a chemical change, whereas roasting is a thermal treatment that is used to produce a physical change.
What Happens in the Blast Furnace?
The blast furnace is a large and tall structure that is used to produce iron from ore. The blast furnace is fueled by coal, which is burned to produce heat. The heat is used to produce a chemical reaction that converts the ore into iron.
What is Wrought Iron/Malleable Iron?
Wrought iron is an iron alloy with a very low carbon content, in contrast to cast iron. It is a tough, malleable, ductile, and corrosion-resistant material.
Iron Extraction Procedure
The process of extracting iron from its ore involves crushing the ore to a powder and then heating it in a furnace with a carbon source. The carbon reacts with the oxygen in the ore to create carbon dioxide gas, which leaves the furnace through the smokestack. The molten iron is then poured into molds to cool and solidify.
