Description
Summary:Bottom ash (BA) samples from a municipal waste incinerator in Poland were collected to investigate metallic components. Numerous metal-rich phases were present in the BA as a part of the incombustible waste fraction, concentrated and modified during thermal treatment. Metallic components in the BA occurred as heterogeneous assemblages of elements with various oxygen content. Fe- and Al-rich occurrences prevailed other types of compositions (e.g. Cu-, Zn- and Ti-rich). Elements in metal-rich phases co-occurred with each other (e.g. Fe occurred with Si, Ca, P, Al and Ti; Al occurred with Fe, Si and Ca; Zn occurred with Ca, Al and Si).
