Magnetite Uses - Education - Micrex Development Corp

The heavier specific gravity of magnetite aggregates allow a more aggressive backwash in the cleaning phase without loss of product, and because magnetite is magnetic it can be easily scavenged back from waste water streams for reuse. Magnetite is an essential part of the "heavy media" process in coal mining.

Magnetite - an overview | ScienceDirect Topics

Dilip Kumar, Deepak Kumar, in Sustainable Management of Coal Preparation, 2018. Abstract. Magnetite is widely used in most dense-medium processes in the coal industry because of its higher specific gravity, stability in suspension, lower viscosity, and easy availability, recovery and reuse. To keep the suspension at the desired specific gravity and low viscosity, it is necessary …

ISO 8833:1989(en), Magnetite for use in coal preparation ...

In coal preparation, the mineral magnetite (FeO, Fe 2 O 3) has become the most commonly used material, not only because it fulfils all the above criteria, but also because of its worldwide occurrence either as an iron ore or as a by-product of mining operations for other minerals. Like any mineral, magnetite rarely occurs in the pure state and ...

Sextets belong to hematite, magnetite, and hydrogoethite. Sextet C1 corresponds to the octahedral position of the ferric iron of hematite. Sextet C2 is due to Fe 3 + ions of the tetrahedral position in the magnetite lattice, while sextet C3 is due to ions of the octahedral position. The area ratio of tetrahedral and octahedral iron ions in the spectrum differs from 0.5 …
