Zinc Mining. The most commonly available ore used in the extraction of Zinc is called Zinc Blende also known as Zinc Sulphide (ZnS). Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas.

Iron is the most widely used metal in the world, mainly in the form of steel. If you've used any form of transport today, it probably contained plenty of iron. Steel is used to make most cars, buses, and trains.
Iron ore (source of iron), coke (source of carbon) and limestone are added at the top of the blast furnace; Hot air is blasted from the bottom of the furnace to the top; Oxygen in the air reacts with coke to form CO 2, which in turn reacts with the coke again to from carbon monoxide; Carbon monoxide is a reducing agent and thus turns iron oxide into iron.

IGCSE AID. C10.3 Extraction of Metals. Describe the essential reactions in the extraction of iron in the blast furnace. An ore is a rock from which metals can be extracted. The main ore of iron is hematite, which contains large amounts of iron(III)oxide. It is reduced by carbon to for iron, but this takes place in a huge blast furnace.
The main iron ore is called haematite. Haematite is iron(III) oxide Fe 2 O 3. The iron ore contains impurities, mainly silica (silicon dioxide). Limestone (calcium carbonate) is added to the iron ore which reacts with the silica to form molten calcium silicate in the blast furnace. The calcium silicate (called slag) floats on the liquid iron.
Extraction and uses of Iron Reduction is used to extract iron from its ore (haematite) which is mainly iron(III) oxide. The iron ions are reduced to iron atoms, using carbon. This is oxidised to form carbon dioxide. iron(III) oxide + carbon iron + carbon dioxide 2 Fe2O3(s) + 3C(s) 4 Fe(l) + 3 CO2(g) The process happens in a blast furnace.
