“…Platinum-group element ores are mainly associated with ultramafic-mafic rocks and, little is known about the interaction of Pt-bearing aqueous solutions with sulfide minerals [7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Platinum-group element deposits of hydrothermal origin exist, and mechanisms of hydrothermal transportation of PGEs [9][10][11][12], including the biological transport and transformation [21][22][23][24] have been studied since the end of the 1980s.…”

The interaction of aqueous solutions bearing platinum-group elements (PGEs) with sulfides is important for understanding the formation and weathering of PGE ore deposits, mineral processing, and synthesis of nanomaterials. Here, the surface species formed upon the contact of the main sulfide minerals (pyrite, pyrrhotite, galena, chalcopyrite and valleriite) with the solutions of H 2 PtCl 6 (pH 1.5, 20 • C) have been studied using X-ray photoelectron spectroscopy (XPS). Uptake of Pt increased gradually with increasing interaction time, and depended, as well as the composition of immobilized products, on the mineral nature and the state of its surface, e.g., the chemical pre-treatment. The highest rate of Pt deposition was observed on galena and valleriite and the lowest on pyrite and pyrrhotite. The preliminary moderate oxidation of pyrrhotite promoted Pt deposition, which, however, was hindered under harsh reaction conditions. The pre-oxidation of pyrite in all cases resulted in a decrease of the Pt deposition. Initially, Pt(IV) chloride complexes adsorb onto the mineral surface, and then the reduction of Pt(IV) to Pt(II) and substitution of chloride ions with sulfide groups occur forming sulfides of Pt(II) and then, Pt(IV). The reduction of Pt species to the metallic state was observed at valleriite after 24 h, probably due the negative charge of the sulfide nanolayers of this sulfide-hydroxide composite mineral.

Frank Reith's research legacy (Fig. 1) is the discovery that bacteria make a 'home' on gold grains and these microorganisms render gold mobile in the surrounding environmentbelying the yellow metal's reputation for inertness and resistance to corrosion (Fig. 2). Frank was the first to integrate molecular characterisation with the 'classic' geochemical and morphological characterisation of placer gold grains, a radical step-change from the geological literature. His interdisciplinary approach to research integrated the latest cutting-edge techniques in chemical, spectroscopic, molecular and proteomic analysis. Frank had the gift of exciting people, of all walks of life, about his research. Throughout his career, he loved collaborative research and developed a vast and diverse network of interdisciplinary collaborators (friends) across the globe. Although his academic career was relatively short, Frank published >75 scientific papers, listed in the Appendix. To the broader geoscience community, Frank was a world-leading geomicrobiologist, fascinated by gold and devoted to delineating the interactions between bacteria and precious metals. He described himself more simply as, "the man with the gold bug". The man Frank Reith, the elder of two children, was born on the 11th of June 1972 to Elke and Ernst-Wolfgang Reith, a family of wine makers in the Rhine-Hesse region, Germany. Frank grew up in the town of Woerrstadt and attended High School in Nieder-Olm. After fulfilling his civil service obligations as an ambulance driver, he attended the University of Bayreuth and graduated in 1999 with a Master's Degree in Ecological Fig. 1.
