The following diagram shows how iron is extracted from iron ore in a blast furnace. Scroll down the page for more explanations on extraction of iron. Extraction of iron Very unreactive metals are found directly in the ground as elements, eg. gold. Most metals are found in ores where they have reacted with other elements.

Students can perform reduction experiments themselves such as reducing iron oxide to iron. A favourite class practical lesson is extraction of iron on a match head. Begin by showing a sample of the iron ore haematite. Discuss sources of iron ore and mines such as the former Florence iron mine in Egremont, Cumbria which closed in 2008.

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

Carbon may also be left in the metal as an impurity. Sometimes this can be removed afterwards (for example, in the extraction of iron); sometimes it can't (for example in producing titanium), and a different method would have to be used in cases like this. Other more reactive metals can be used to reduce the ore.

Metallurgy of Zinc. The principal ore of zinc used for its extraction is Zinc blend (ZnS) ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200K 1200 K to obtain zinc oxide (ZnO) ( Z n O). It is then reduced to Zn Z n by coke ...

The basic extraction of metals from ores has the following steps. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverisation.

This method is used for the extraction of iron from the coarse-grained haematite. The geological grade of hematite deposit is relatively high (about 50%), but the ore body is thinner and has more interlayers, and the ore will be depleted due to the mixing of waste rocks during mining.

The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.
