Iron | Introduction to Chemistry

Iron chemical compounds, which include ferrous (Fe 2+) and ferric (Fe 3+) compounds, have many uses. Iron oxide mixed with aluminium powder can be ignited to create a thermite reaction used in welding and purifying ores. Iron forms binary compounds with the halogens and the chalcogens.

An Introduction to Iron - AZoM

2001-7-30 · Significant amounts of iron are also present in the sun and several types of stars. Iron occurs naturally in the form of meteorites called siderites. Hematite (Fe 2 O 3), magnetite, magnetic pyrites, and iron or carbonates are the common ores of iron. Iron is derived from its ores by fusing to eliminate the sulfur, oxygen, and impurities.

Ferrous metallurgy - Hyperleap

Metallurgy is subdivided into ferrous metallurgy (also known as black metallurgy) and non-ferrous metallurgy (also known as colored metallurgy). It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Pig iron is an intermediate product of the iron industry, also known as crude iron, which is obtained by smelting iron ore in a blast furnace.
