Complexation reactions at the mineral–water interface affect the transport and
transformation of metals and organic contaminants, nutrient availability in soils, formation of …

The most characteristic feature of hydrothermal deposits of gold is its intimate association
with pyrite. Microscopically visible gold occurs in pyrite ore as metal particles of> 0.1 µm in …

Publisher Summary The chapter discusses various techniques and applications of scanning
electrochemical microscopy (SECM), one of the scanning probe microscopies (SPM) in …

Arsenic is a toxic metalloid whose mobility and availability are largely controlled by sorption
on sulfide minerals in anoxic environments. Accordingly, we investigated reactions of As (III) …

Pristine pyrite fracture surfaces, exposed for 7 h to water vapour at low pressure (10− 5 Pa),
display no change to their Fe (2p) or S (2p) X-ray photoelectron (XPS) spectrum, but oxygen …

The interaction of aqueous U (VI) with galena and pyrite surfaces under anoxic conditions
has been studied by solution analysis and by spectroscopic methods. The solution data …

The contaminant of most concern in groundwater at the Oak Ridge Y-12 Plant's Bear Creek
Valley Characterization Area is soluble uranium. The removal mechanism of soluble …

The retention of radionuclides by interaction with mineral phases has significant
consequences for the planning of their short-and long-term disposal to geological systems …

The disproportionation of aqueous Au (I) chloride complexes at elevated temperature has
been investigated experimentally using the solubility method. At 300° C, the dominant gold …

The adsorption of gold by pyrite, pyrrhotite, and mackinawite from solutions containing up to
40 mg/kg (8 μm) gold as hydrosulphidogold (I) complexes has been measured over the pH …
