How Is Iron Extracted From the Earth? Reference

Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast

Metals below carbon can be extracted from the ore by reduction using carbon, coke, or charcoal. Gold and silver often do not need to be extracted. They occur native. The reactivity of a metal determines the method of extraction. lead silver

BBC Bitesize GCSE Chemistry (Single Science) Iron

We can see from the table that reactive metals, such as aluminium, are extracted by electrolysis, while a less reactive metal, such as iron, may be extracted by reduction with carbon. Because gold it is so unreactive, it is found as the native metal and not as a compound. It does not need to be

Why is iron easier to extract the aluminum

Aluminium is then extracted by electrolysis at a reduction plant, or smelter. The ore is first converted into pure alumina by the Bayer Process which involves heating in caustic soda. The aluminum trihydrate dissolves leaving a residue of insoluble iron and titanium oxides called red mud. The aluminum trihydrate is dried to produce alumina which is

What metals are extracted by electrolysis? Answers

Apr 13, 20070183;32;Reduction occurs at the cathode and oxidation at the anode. All metals above iron in the reactivity series (that is, potassium, sodium,calcim, magnesium and aluminium) are extracted by electrolysis. This is because they form too stable compounds that are difficult to reduce using simple reducing agents like carbon

BBC GCSE Bitesize Making iron

Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron oxide. The oxygen must be removed from the iron oxide to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions. Carbon is more reactive than iron
