Investigation of high-temperature slag/copper/spinel interactions KU Leuven Ghent University
An important cause for the mechanical entrainment of copper droplets in slags during primary and secondary copper production is their interaction with solid spinel particles, hindering the sedimentation of the copper droplets. In the present study, the interactions between the three phases involved (slag–Cu droplets–spinel solids) were investigated using an adapted sessile drop experiment, combined with detailed microstructural investigation of ...
