How is Iron Refined from Ore (with pictures)

Oct 15 2019 · Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron one must deoxygenate the ore leaving only iron atoms behind which is the essence of the refining process. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to.

Bauxite Mining and Alumina Refining Process Description

Bauxite Mining and Alumina Refining Process Description

The bauxite ore contains aluminum trihydrate (Al(OH) 3). Alumina refining produces alumina (Al 2 O 3) from the bauxite ore by exploiting the reversible reaction of the Bayer process 1–3 The reaction is firstly driven in the sodium aluminate (NaAlO 2) direction by the addition of caustic soda (NaOH) to bauxite. Bauxite residues are then
