    Published: 9 June 2022
    Abstract: Globally, roughly 1.75 million tons of waelz slag per year are produced from 35 waelz kilns. The increasing costs for landfilling, changing environmental concerns and a focus on sustainable production foster an investigation of this by-product to investigate if at least parts of it can be used as a raw material. Waelz slags are highly variable in t... Show More
