Dust masks worn by load haul dump operators passed 200 mg of filter loading in an average of 1.7 hours, and continuous miner, shuttle car and roofbolt operators reached the same point within two to five hours. Every mask failed laboratory fit testing. An eight hour service life is too long.
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.
