Extraction of metals (a) describe the ease of obtaining metals from their ores by relating the elements to their positions in the reactivity series Recycling of metals (a) describe metal ores as a finite resource and hence the need to recycle metals, e.g. the recycling of iron (b) discuss the social, economic and environmental issues of recycling …

A great animated powerpoint with accompanying worksheet explaining the extraction of iron.

IRON • The total body iron content of normal adults is 4.3 and 2.3gms in men and women respectively. • Iron is an essential mineral that carries oxygen and forms part of the haemoglobin in our red blood cells and myoglobin in muscle. • Iron is primarily stored in the liver, spleen and bone marrow in the form of ferritin.

This kind of iron is called Cast Iron and has a slightly lower carbon content 2 – 3 %. This is even harder than pig iron. Wrought Iron/ Malleable Iron. Wrought iron is the purest form of iron available commercially available and is prepared from cast iron by heating cast iron in a furnace lined with Haematite (Fe 2 O 3). The Haematite reacts ...

The extraction of metals involves multiple stages including separating the metal from the ore and purifying it. Aluminum extraction involves electrolysis to separate the aluminum ions from oxygen in the ore bauxite. Metals are finite resources so recycling is important as it allows continued use of metals and extends the life of ore deposits.
