GCSE CHEMISTRY The Manufacture and Uses of Lime

When limestone (calcium carbonate) is heated, at about 1000 °C it undergoes thermal decomposition. It loses carbon dioxide and turns into quicklime (calcium oxide). calcium carbonate calcium oxide + carbon dioxide. CaCO 3 (s) CaO (s) + CO 2 (g) The reaction is carried out in specially constructed lime kilns (a kiln is a high temperature oven). Limestone is added at the top and quicklime is

Processes and Procedures in the Extraction of Iron

15/02/2021· The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.
