Metallurgical slags are a byproduct of metal ore smelting and are classified as waste from thermal processes. The production of one tonne of copper or lead generates approximately two tonnes of slag. During thousands of years of metallurgy, vast amounts of slags have been produced and deposited in slag heaps. Although slags contain significantly less metal than the corresponding ores, their metal concentrations are still higher than those found in barren rocks. Slags have gained increasing significance in the search for alternative metal sources and with growing environmental awareness. Due to their similarity to igneous rocks, they can be studied using classical methods of Earth sciences. Results of those studies support the development of metal recovery technologies and enhance our understanding of element cycles in environments affected by human activity. Moreover, research on historical slags provides valuable insights into the development of ancient civilizations. Studying slags not only contributes to better management of metallurgical waste but also offers important knowledge about both the past and future use of mineral resources.
