· Galena (PbS) is an important and abundant source of Pb (Hu et al., 2020b) and mining and processing of galena increase yearly with increasing Pb demand (Akcil and Ciftci, 2003, Yang et al., 2013). Galena often coexists with other sulphide minerals such as sphalerite (ZnS), pyrite (FeS 2 ) and oxidised minerals ( Luo et al.,
