  Physical separation of iron ore: magnetic separation

  202211 · Abstract This chapter introduces the principle of how low-grade iron ores are upgraded to high quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth and can be readily extracted by low-intensity magnetic separators from magnetite ores. On the other hand, oxidized iron ores …

  Comparative study on grinding kinetics behavior of …

  Vanadium-titanium magnetite underwent closed circuit crushing before and after microwave pretreatment. Subsequently, batch grinding tests were conducted on the crushed products, with varying grinding times. Ultimately, the m -order grinding kinetics model of the ore was established both before and after microwave pretreatment.
