Steel production is currently the largest industrial source of atmospheric CO2. As annual steel production continues to grow, the need for effective methods of reducing its carbon footprint increases correspondingly. The carbonation of the calcium-be

Although the rare earth elements have been thought by many to be immobile in hydrothermal fluids, we have known since the first attempts to separate them in the early nineteenth century that they are soluble in aqueous solutions. Driven by a need to

The volumetric properties of H2O–H2S fluid mixtures have been determined experimentally at temperatures of 150 to 400 °C and pressures up to 240 bar. Using these data and existing equations of state, we have developed a thermodynamic model for H2O

This experimental study sheds light on the complexation of gold in reduced sulphur-bearing vapour, specifically, in H2O– H2S gas mixtures. The solubility of gold was determined in experiments at temperatures of 300, 350 and 365 C and reached 2.2, 6

Although gold is a noble metal and is effectively insoluble even in strong acids, we have known for nearly 500 years that it can be concentrated to mineable levels by being transported as dissolved species in crustal fluids (indeed, most economic gol

The solubility and speciation of the assemblage MoO2–MoO3 in water vapour were investigated in experiments conducted at 350 C, Ptotal from 59 to 160 bar and fHCl from 0 to 3.4 bar (0–2.0 mol%). Measured solubility at these conditions ranges from

The solubility of gold in H2S gas has been investigated at temperatures of 300, 350 and 400 °C and pressures up to 230 bars. Experimentally determined values of the solubility of Au are 0.4–1.4 ppb at 300 °C, 1–8 ppb at 350 °C and 8.6–95 ppb

The solubility of molybdenum trioxide in liquid–undersaturated water vapour has been investigated experimentally at 300, 320, and 360 � C and 39–154 bars. Results of these experiments show that the solubility of MoO3 in water vapour is between

The solubility of metallic mercury in dodecane, octane and toluene has been investigated experimentally at temperatures up to 200°C and pressures up to 6 bars (toluene). The equilibrium Hg concentrations are very similar in octane and dodecane, reac
