Presenting a New Method Based Upon the Usage of Magnetic Fields for Solving the Problem of Sedimentation & Sludges & Impurities of Coal

In This Letter ,the main aim is presenting an applied and instrumental method for surveying the problem of sediments,sludges and some common impurities of coal by using a novel method,that is,the magnetic field.also, in this letter,the effect of high gradient & high strength magnetic fields on coal is investigated. Experimentation was carried out using a high intensity (HI) magnetic separator and coarser coal fractions were treated on a permanent magnetic roll separator capable of producing exceptionally high magnetic field gradients.Total sulphur and ash removal data is given for coal fractions after magnetic treatment plus X—ray diffraction and magnetic profile analysis provides identification of the mineral constitution of the ash fraction of the coal.
