The extraction of iron from its ores is quite a technical process The iron ore is first roasted in air to produce ironIII 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

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore Tailings are distinct from overburden which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed
