6.2.5.4 Scanning electron microscope (SEM) At the end of experiments, slags grain were observed with respect to surface changes using
Scanning Electron Microscope (QEMSCAN 650F) at 10-20 kV and high vacuum working
mode.
6.2.5.5 Visual MinteQ modelling The geochemical simulation was performed using Visual MinteQ modeling software (version
3.1) in order to determine the degree of saturation of the leaching solutions with respect to
possible secondary precipitates. The modeling was performed using the chemical composition
of the leaching solution for every incubation time.
