  • Dry Magnetic Separation of Iron Ore of the Bakchar Deposit

    As noted above a Bakchar iron ore relates to the high grade ores containing in natural form up to 43.9 of iron But chemical analysis indicated that before the magnetic separation that ore had already contained 46.2 of iron Probably this is explained by centralization of the ferruginous particles in a selected fraction –0.63 0.5 mm A complex shape of the curve Fig 4 is explained by the peculiarities of the response of the ferruginous particles to a magnetic field of the separator At relatively low 3A the most iron containing particles are separated primarily as they have a maximum magnetic susceptibility Further with the increase of the current in the winding particles of the gangue begin to move to the concentrate more and more reducing the quality of the concentrate Thus at 5A the iron content in the concentrate is only 1.5 more than its content in the original ore Iron content in the concentrate increases considerably with the further increase of the current strength because iron ore
