Refining – Various Methods
Usually, it is a copper refining process against impurities. Firstly, the impure copper is kept in an anode furnace for two steps of refining. Next, iron and sulphur release in the form of iron oxide and sulphur oxide by blowing air. In this step, the iron oxides release from copper and gaseous sulphur oxide emits from furnace by off-gas system.

The Making of Iron & Steel
Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent. The metallic iron produced by such a furnace

Processes and Procedures in the Extraction of Iron
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. The temperature inside the blast furnace varies from about 2000*C

process of purifying iron ore
To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to.
