    Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, separation data generally are byproducts of other projects; and second, this study requires a large amount of patience and is unusually tedious. Indeed, we suspect that most minerals probably are never investigated for this property.

  • MAGNETIC DRUM SEPARATOR magnetic separation equipment

    What is magnetic separation method for concentration of ore? This method of separation is used when either the ore particles or the gangue associated with it possess magnetic properties. For example, chromite Fe(CrO2)2 being magnetic can be separated from the nonmagnetic silicious gangue by magnetic separation.

  • Oxidation of pyrite in an anoxic atmosphere USGS

    Pyrite (FeS2) inclusions in coal, when heated in an oxygen deficient atmosphere (approximately 1% oxygen), become coated with magnetic Fe3O4 due to oxidation. Most of the FeS2 can thus be removed from the coal by magnetic separation to reduce the sulphur concentration.

    The throughput of pyrite extraction from coal using the conventional magnetic separation method can be effectively improved by increasing the magnetic susceptibility of pyrite. The electromagnetic characteristics and absorption response of fine highsulfur coal were studied to evaluate the strengthening effect of microwave treatment on the magnetic susceptibility of pyrite.
