Effect of Milling Method on Chromite Surface Composition and Sintering
- 49 Downloads
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 Å there is magnesium silicate entirely screening chromium spinelid at a chromite particle surface subjected to fine milling.
