Treatment of Sulphate Rich Effluents with the Combined Electrolytic/Biological Process
2003
Laboratory work on producing hydrogen by electrolysis as the energy source for sulphate reducing bacteria, aimed at cutting the running cost of treating sulphate rich mine water.
What this report foundHydrogen for biological sulphate removal can be generated on site by electrolysis more cheaply than it can be bought.
R1500,00
Hydrogen for biological sulphate removal can be generated on site by electrolysis more cheaply than it can be bought. Stainless steel electrodes in acid mine drainage gave hydrogen at about a third of the bought in price while oxidising ferrous iron to ferric, which helps downstream treatment. Iron and zinc electrodes dissolved too quickly to be viable.
Characterization of Spontaneous Combustion Emissions
2005
Aircraft and ground monitoring at a working colliery in summer and winter, measuring trace gases and particulates from spontaneous combustion, for air quality management and mine planning.

Aircraft and ground based measurements at Kleinkopje Colliery showed spontaneous combustion to be a significant source of fine particles, with PM2.5 concentrations 91 per cent higher inside a combustion plume than outside it. Sulphur dioxide, nitrogen dioxide and carbon dioxide were also raised in plume, and benzene and toluene were detected. Average particle size was below one micron.
