Aqueous metal complexes play an important role in controlling metal transport and deposition in a wide range of natural and engineering situations, including hydrothermal fluids responsible for the formation of most of the world’s

Cu, Au, Ag, Pb and Zn deposits; corrosion in power plants; and hydrometallurgy. The nature of the complex affects the stability of the dissolved metal ions, and hence the solubility of metals in the solutions.

Setting up the mAESTRO cell to study metal speciation at temperatures from ambient to 600 oC and pressures to 600 bar (ie 600x atmospheric pressure).

Commissioning of the mAESTRO autoclave at the Australian synchrotron, October 2009.
