Difference Between Magnetite and Hematite Definition

Difference Between Magnetite and Hematite | Definition

Jan 31, 2018· If a mineral deposit is composed of a metal that can be extracted using existing technological methods, then it is called an ore. Magnetite 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.

But, there are two classifications of magnetic particles, strongly magnetic particles, such as iron and magnetite, and weakly magnetic particles, such as rutile, ilmenite, and chromite. Strong magnetic particles may be easily separated with a separator having a low intensity magnetic field of 400 ...

Investigation of Efficiency of Magnetic Separation Methods

Investigation of Efficiency of Magnetic Separation Methods

In this research, the efficiency of magnetic separation methods for processing of a low-grade iron pigments ore (red ochre) has been studied. Based on the mineralogical analyses (XRD), thin section and polish studies, the reserve is an iron sedimentary deposit with an average Fe grade of %31.3. The most valuable minerals are Hematite and Goethite and main gangue minerals are Calcite and Quartz.

Magnetic separation is a simple, fast and efficient procedure and the whole separation process can be performed in the same tube. Large differences between magnetic permeabilities of the magnetic and nonmagnetic materials can be exploited in developing highly selective separation methods. The separation procedure can easily be scaled up if large quantities of living cells are required.

Magnetic separation is the only effective way of separating the valuable components of iron ore from the diamagnetic inclusions so far as the extractable iron compounds have a high magnetic susceptibility (as a rule, 20 90·10-7 m3/kg8)....
