Experimental Study on Oxygen-Enriched Sintering of …

 · The main components of the sintered ore are slightly changed after oxygen enrichment time, but the FeO content in the finished sintered ore is reduced from 6.50% to 5.95%. These characteristics are caused by the more adequate fuel combustion during oxygen-enriched sintering, which decreases the CO produced by incomplete combustion of coke.

Sintering Characteristics of Indian Chrome Ore Fines

 · Chrome ore concentrate consists of high-temperature melting oxides such as Cr2O3, MgO, and Al2O3. 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 1300 °C to ...
