10%· 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.
We claim: 1. A process for beneficiating chromite ores, comprising: reacting chromite ore with at least one sulfur oxide selected from the group consisting of sulfur dioxide and sulfur trioxide and oxygen by passing a gaseous stream including a sulfur oxide and oxygen about the chromite ore at temperatures in the range of approximately 300°-1000° C. or higher; and
