Kinetics of reduction and oxidation reactions during pyrometallurgical metal extraction

Abstract

The article deals with a sophisticated approach to the study of basic kinetic dynamic process in metal production. It is concerned with three agendas: study of reduction reactions of iron oxides and carbon as reducing agents with secondary created oxides; study of the effect of catalyst occurrence on the reaction space; study of the effect of variable temperature and pressure gradients on the processes. The main experiments were carried out in the newly established Laboratory for Research on High Temperature Properties equipped with testing setup and upgraded with interpretive model system, enabling a generalization of experimentally obtained information to theoretical conclusions about processing of non-standard alternative and waste materials.
