Sintering Characteristics of Indian Chrome Ore Fines ...

Oct 01, 2009  Chrome ore concentrate consists of high-temperature melting oxides such as Cr 2 O 3 , MgO, and Al 2 O 3 . The presence of these refractory constituents makes the ore a very high melting mineral. Hence, it is difficult to produce sinter from chrome ore by a pyrometallurgical route. Currently, chrome ore is ground to below 75 μm, pelletized, heat hardened through carbothermic reaction at
