SOLID STATE REDUCTION OF CHROMITE IN HIGH CARBON FERROCHROMIUM-CHROMITE COMPOSITE PELLETS

Abstract: In this paper solid state reduction of high carbon ferrochromium-chromite composite pellets in the temperature range of 900-1350°C was investigated. A two stage reduction mechanism is proposed. The first stage is likely to be controlled by the chemical reaction with activation energy of 127.2kJ/mol. In the second stage, solid state diffusion of carbon through the reaction product ...

DIRECT REDUCTION OF SARCHESHME COPPER SULFIDE CONCENTRATE WITH CARBON IN THE PRESENCE OF LIME

Abstract: The direct reduction of copper sulfide concentrate from Iranian Sarcheshme deposits with carbon in the presence of lime was investigated in the temperature range of 800-1000 ºC. The reduction kinetics was determined by means of weight loss measurements. It was found that the rate of reaction increased considerably with increasing the temperature. The kinetics was also improved whe...
