Galena (PbS) is one of the most important base metal sulfide minerals and is a narrow band gap semiconductor. Galena often occurs with other sulfide minerals, such as chalcopyrite or pyrite (Zárate et al., 2012).Oxidation, reagent adsorption, and reactions between sulfide minerals and aqueous solution play a key role in mineral processing (Ralston, 1991).The ore mineral galena (PbS) contains essentially no uranium and thorium. Its lead isotopic composition is defined by 206 Pb (derived from 238 U), 207 Pb (derived from 235 U), 208 Pb (derived from 232 Th), and 204 Pb (stable). The U-Th history is simply inherited when galena forms and remains unchanged with passing time.Galena (an ore) is partially oxidized by passing air through it at high temperature. After some time, the passage of air is stopped, but the heating is continued in a closed furnance such that the contents undergo self-reduction.
