• Effect of Milling Method on Chromite Surface Composition

     · Milling of chromite concentrate is studied in equipment with different milling methods and energy intensity. It is established that milling gives rise to a different chromite fine particle surface structure different nature and amount of microdeformation within particles and different chemical activity. Milling has almost no effect on material phase composition.
