How to Recover Iron from Magnetite: 4 Methods and Stages

Stage 4 | Magnetite dehydration. Since the iron concentrate after separation contains some water, dehydration treatment is required. 1 The separated iron concentrate slurry flows into the thickener for sedimentation to remove a large amount of water. 2 After drying and dehydration in a dryer, the dried iron concentrate powder is obtained.

It is obvious that in the pelletized part, hematite and magnetite exist in two different areas. This is because, during the sintering process, the magnetite on the outer layer of the pellet was oxidized to hematite, but the magnetite in the inner layer of the pellet recrystallized at high temperatures.

Induration Process of Pellets Prepared from Mixed Magnetite–35% ...

The induration process for green pellets involves 4 main stages: (1) drying, (2) preheating, (3) heating and (4) cooling. In the drying stage (105–260°C), water is removed from the pellet in a controlled process to avoid cracking. During preheating (260–845°C), oxidation of the magnetite and decomposition of carbonates occur.
