Extraction of Metals (Metallurgy) Overall Science

2020-10-9  Metals are present in the ore in combination with other elements. From the ore, metals are obtained by the process of reduction. Carbon, hydrogen and metals like sodium, aluminium, magnesium are good reducing agents. The method of reduction and the nature of reducing agent to be used for the reduction depends upon the activity of the metals.

2021-2-15  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.
