Feb 08, 2021· The particular method chosen for the extraction of metal depends on the stability of the ore, which also depends on the position of the metal in the activity series. Electrolytic reduction process is used to reduce the more reactive metals(from their ores) that have very negative electrode potential values and a great tendency to exist as positive ions. It is difficult

Feb 15, 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.
