Unlocking the Power of Magnetic Separation Method
The magnetic separation method is one of the most effective and easiest methods of getting the iron ore from the other materials. This technique is very useful in high throughput operations where large volumes of slurry are processed in order to separate the iron ore from the non-magnetic materials.
How to Recover Iron from Magnetite: 4 Methods and Stages
Magnetite is an iron oxide ore, which belongs to the equiaxed crystal system, and its chemical formula is Fe3O4. The Mohs hardness of magnetite is 5.5~6.5. Like hematite, it has strong magnetism. In ancient times, it was also called a magnet. Magnetite is often formed in igneous, metamorphic, or granitic pegmatites, high-t…
