Abstract
Processing of secondary resources is a relatively new field in metallurgy. In addition to the direct processing of metallurgical dusts, an alternative interest is in the combined processing of various types of resources, including dusts either with high energy contents (carbon and hydrocarbons containing dusts) or with valuable metal contents. The first step in analysing the new metallurgical routes of materials processing is the thermodynamic approach, which gives a quick look at the feasibility and limitations of the defined new processing methods. In the present study, two examples of potential pyrometallurgical treatments for industrial dusts are analysed on the basis of the thermodynamic and thermochemical principles. The aim of this paper is to show the important role of thermodynamic/equilibrium predictions for the design and planning of experiments and the determination of optimal processing conditions.
