Effect Of Milling On The Beneficiation Of Chromite

Apr 22, 2015 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. Within a layer more than 50 ...
