Solid-State Reduction of Chromite Concentrate - Melting of Prereduced Chromite
, 1995 The solid state reduction of a chromite concentrate from Northern Greece in the temperature range 1100-1470 degrees C has been studied. The degree of reduction of chromite by graphite was found to increase with increasing temperature, time, and carbon addition.
