Abstract

The article deals with the thermodynamics of the process in the ore-thermal processing of copper smelting slag, the experimental study of ore-smelting processing of copper smelting slag, and the development of a mathematical model for obtaining iron-containing alloys from copper slag, development of a technological scheme for obtaining iron-containing alloys from copper slag-information on the application and approbation of the technology in the production of the results.The assessment of the possible direction of the carbothermic reactions that take place between the oxidised compounds in the slag and the carbon was carried out by changing the thermodynamic values ​​of the system. Thermodynamic analyses were performed, taking into account the temperature dependence of the isobaric-isothermal potentials (Gibbs free energy).

Keywords: Carbothermal reduction, pig iron, copper slag, thermodynamic analyses
