Extraction of iron, tin, lead. zinc and various ferro-alloys is achieved by carbotherrnic reduction of oxide ones. The production of pig iron in the blast furnace is by far the most noteworthy process of extraction due to its large tonnage. The most abundant ore of iron is hematite, where iron is present as the mineral. FeZOJ.
29 Nov 2015 Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air.
Creating steel from low-grade iron ore requires a long process of mining, crushing, separating, concentrating, mixing, pelletizing, and shipping. The process of mining low-grade iron ore, or taconite, requires massive resources. Heavy industrial mining equipment, expansive mines, and a skilled labor pool are all required.
Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace. The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe2O3.
EXTRACTION OF METALS. Occurrence • ores of some metals are very common (iron, aluminium). • others occur only in limited quantities in selected areas. • ores need to be purified before being reduced to the metal - this adds to the expense. • high grade ores are therefore cheaper to process. Theory. The method used
22 May 2009 The Step by Step Process of Extracting Iron from its Ore using the Blast Furnace with details of Chemical Reactions. Question Answers based on the process of e

7 Nov 2007 The blast furnace. You need to be able to describe how iron is extracted in a blast furnace, including the raw materials, reactions, and the formation and uses of slag. A blast furnace is a huge steel container many metres high and lined with heat-resistant material. The solid raw materials (iron ore, coke and
To extract the iron from iron(III) oxide, we remove the oxygen chemically. The iron(III) oxide must be reduced. This is done in a blast furnace. The haematite is fed into the top of the furnace along with coke (a cheap form of carbon, made from coal) and limestone.
26 Apr 2010 Extraction of Metals. Learning Objectives. • Describe the ease of obtaining metals from their ores by relating the elements to their position in the reactivity series. • Describe the essential reactions in the extraction of iron from Haematite using the blast furnace. Recap. • Reactivity series. • Reaction of metals
