Mass balance at partial run of quartzite carbothermal reduction

Metalurgija, 2016
Mass balance for the process of incomplete carbothermal reduction of SiO2 to SiC thermogravimetric studies was presented. Tests were performed for the molar ratio of C/SiO2 = 3 at a temperature of 1 500 °C under an argon flow in the range from 0,1 to 3,4

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.
