  • the process of obtaining pig iron from iron ore is called

    Nov 14, 2020· The extraction of iron from itsoresis quite a technical process. Theiron oreis 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.
