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.

Iron in Chalcopyrite is removed as iron silie slag. Most of the sulphur in Chalcopyrite turns into Sulphur dioxide (SO 2). The reaction of these processes can be written as: 2CuFeS 2 +2SiO 2 +4O 2 → Cu 2 S+2FeSiO 3 +3SO 2. The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and
