Roasting of sulphide using carbothermal reduction

, 2016
The carbothermic reduction process is a direct reduction of sulfides. It allows a roasting in which higher concentrations of metals such as molybdenum are obtained by using both a reducing agent (in this case, carbon C) and a sulfur scavenger, such as CaO so as to prevent air toxic gases pollution such as SO2.

THERMODYNAMICS OF CARBOTHERMAL REDUCTION PROCESS COPPER SLAG

Journal of Chemical Technology and Metallurgy
The article analyses the thermodynamic laws of processing iron-based compounds contained in copper production slag using the method of carbothermic recovery. Evaluation of the probable direction of carbothermic reactions occurring between oxidized compounds and carbon in the slag was carried out by changing the thermodynamic values of the system.
