Copper metallurgical slags: mineralogy, bio/weathering processes and metal bioleaching

3.1.3 Experimental designs 
Five  major  experiments  were  carried  out  in  frame  of  this  PhD  project.  Those  included:  i) 
mineralogical  characterization  of  slags,  ii)  pH-dependent  leaching,  iii)  leaching  with  soil 
organic  acids,  iv)  bioweathering  experiments  and  v)  bioleaching  experiments.  Experimental 
approaches  designed  for  respective  experiments  are  presented  in  Figures  3.8-3.11  and 
comparison of experimental conditions and analytical techniques is summarized in Table 3.1.
