Autor: Michaela Ruzickova, Martina Laubertova, Jarmila Trpcevska, Alexandra Kollova, Zita Takacova, Tomas Vindt

Publikováno v: Engineering Proceedings, Vol 64, Iss 1, p 1 (2024)

Pyrometallurgical copper production is carried out in thermal aggregates. Input waste materials with a copper content between 5% and 99% Cu are treated in the individual aggregates. In a shaft furnace, except for molten black copper, slag and shaft f
