Mineral and Technological Features of Magnetite
Mineralogical studies have established that the main iron-bearing mineral is hematite, which contains 69.02 to 70.35% of iron distributed in the ore. Magnetite and hydrogoethite account for 16.71-17.74 and 8.04-10.50% of the component, respectively; the proportion of iron distributed in gangue minerals and finely dispersed iron hydroxides is

Mineral and Technological Features of
Apr 06, 2021It has been found that the main iron-bearing mineral is hematite, which contains 69.02 to 70.35% of iron distributed in the ore. Magnetite and hydrogoethite account for 16.71–17.74 and 8.04–10.50% of the component, respectively; the proportion of iron distributed in gangue minerals and finely dispersed iron hydroxides is very insignificant.

Iron Ores (Hematite and Magnetite) GeeksforGeeks
Nov 07, 2021Magnetite is a ferromagnetic mineral, whereas hematite is a paramagnetic mineral. As a result, these materials can be separated using a low-intensity magnetic separation method. An induced roll magnetic separator is used in this application. The magnetite and hematite mixture is fed to the separator from the top in this method.

Difference Between Magnetite and Hematite Pediaa.Com
Jan 31, 2018Magnetite and hematite are two forms of iron ores from which iron can be extracted. Magnetite contains iron in the form of Fe 3 O 4. Hematite contains iron in the form of Fe 2 O 3. The main difference between magnetite and hematite is that magnetite is ferromagnetic whereas hematite is paramagnetic. Key Areas Covered 1. What is Magnetite

Magnetite Wikipedia
Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 2+ Fe 3+ 2 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. With the exception of extremely rare native iron deposits, it is the most magnetic of all the naturally occurring minerals on Earth.
