Main objectives were to evaluate environmental stability of Cu-metallurgical slags resulting
from different periods of industrial activities and different smelting technologies. Those
included: historical crystalline slag (HS) as well as modern: shaft furnace slag (SFS),
granulated slag (GS) and lead slag (LS). Different approaches undertaken in this PhD work
considered: i) chemical and mineral phase compositions of slags, ii) leaching susceptibility of
slags under exposure to different pH-stat conditions, iii) slags weathering under exposure to
organic acids commonly found in soil environment, iv) bacterially (Pseudomonas aeruginosa)
mediated weathering of slags and v) future application of studied slags for metal recovery by
implementing the bioleaching method.
