Several pyrometallurgical industries encounter production losses due to the attachment of metallic droplets to solid particles in slags. Although scarce, due to experimental challenges, the understanding of this phenomenon is crucial for the development of new technologies to mitigate these losses. This study aims to investigate the attachment of metal droplets to solid particles in slags, with a focus on the role of the slag composition and the particle morphology. The results of this study will provide valuable insights into the mechanisms governing the attachment of metal droplets to solid particles in slags, and will contribute to the development of new technologies to improve the efficiency of pyrometallurgical processes.
