Kinetic Studies on the Reduction of Iron Oxides in Low ...

In a novel method of beneficiation of low-grade chromite ore, nuggets, 25 mm in diameter and 10 mm long, made of chromite ore and coke fines, are subjected to partial reduction. A significant degree of reduction of iron oxide is observed at temperatures of 1373–1523 K up to a reduction time of 240 min, and subsequent magnetic separation is found to enrich the low-grade chromite ore.
