reduced iron consists

Reduction (chemistry) Simple English , the free

Reduction is a chemical reaction that involves the gaining of electrons by one of the atoms involved in the reaction between two chemicals.The term refers to the element that accepts electrons, as the oxidation state of the element that gains electrons is lowered. An example of a reduction is when iron reacts with oxygen, forming iron oxides commonly known as rust.

Iron in diet MedlinePlus Medical Encyclopedia

The genetic disorder called hemochromatosis affects the body's ability to control how much iron is absorbed. This leads to too much iron in the body. Treatment consists of a low iron diet, no iron supplements, and phlebotomy (blood removal) on a regular basis. It is unlikely that a person would take too much iron.

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.

As the volume of the charge is reduced, more is continually added at the top of the furnace. The iron and slag are drawn off separately from the bottom of the furnace. The melted iron might go to a further alloying process, or might be cast into ingots called pigs. The slag is carried away for disposal.

The ores, which are mainly the oxides, are reduced to iron with carbon (coke) at high temperatures in a blast furnace. Over 98% of this is converted directly to steel without even being allowed to solidify after leaving the furnace in which it is made. A relatively small amount is used as cast iron and wrought iron.

Nowadays, the industrial production of iron or steel consists of two main stages. In the first stage, iron ore is reduced with coke in a blast furnace, and the molten metal is separated from gross impurities such as silicate minerals. This stage yields an alloy pig ironthat contains relatively large amounts of carbon. In the second stage, the amount of carbon in the pig iron is lowered
