Gold transport in hydrothermal fluids: Competition among the Cl-, Br-, HS- and NH3(aq) ligands

Gold transport in hydrothermal fluids: Competition among the Cl-, Br-, HS- and NH3(aq) ligands

Since the Au(I) and Au(III) ions are not stable in water, gold transport and deposition in hydrothermal ore fluids are dependent on the identity and stability of the predominant aqueous gold complexes. Gold(I) bisulfide (e.g., Au(HS)2 -) and in some instances Au(I) chloride complexes are widely ackn...
