Magnetite ore (Fe3O4) is a ferromagnetic mineral commonly used in magnetic separation coal washing processes.. Coal washing using magnetite is used to remove contamination from runofmine (ROM) coal, which usually contains rocks, middlings, used consumables and other contamination introduced by the mining process.
For traditional plant we offer the STEINERT WDS wet drum magnetic separators, which are optimised for the recovery of magnetite and ferrosilicon from the heavy media of the sink/float separators. In this way, traditional coal washing can be performed economically, through the recovery of the heavy media.
What is magnetite? Magnetite (Fe3O4), like hematite (Fe2O3), is a form of iron ore. It is a benign and highly magnetic substance used primarily in steel manufacturing and coal washing. Magnetite occurs in nearly all igneous and metamorphic rocks and usually only .
