About
Centre of Metallurgy
Our activity
The Metallurgy Center deals with extractive metallurgy of non-ferrous metals. We develop, among others, technologies for pyrometallurgical processes for the production of metals from
- ores
- concentrates
- scrap and waste
- fire refining of metals
Research offer in the field of extractive metallurgy
- methods of preparing the charge for metallurgical processes through, among others, briquetting, granulation, sintering and roasting
- development of methods for briquetting and granulating various materials together with the selection of the optimal type of binder
- process designs and technical and technological analyses of existing and new processes together with design assumptions
- development of technologies for the recovery of non-ferrous metals from concentrates and all types of secondary raw materials (technology concepts, selection of devices and parameters, design assumptions)
- methods for refining non-ferrous metals from impurities
- methods for obtaining chemical compounds and useful alloys from semi-finished products and waste containing non-ferrous metals
- mathematical modelling and development of algorithms for controlling metallurgical processes and decision support systems

Laboratories
Laboratory of Metallurgical Processes Fundamentals
The Laboratory of Metallurgical Processes Fundamentals analyzes issues related to the theory of metallurgical processes, such as the study of phase systems
Laboratory of Metallurgical Processes
The main idea of the laboratory is to carry out work related to high-temperature processing of primary and secondary materials containing non-ferrous metals using pilot metallurgical units
