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.
Rehabilitation of Mined Land – Soil Compaction Alleviation
2011
Final report on mined land rehabilitation trials comparing pasture species and organic amendments on compacted mine soil against normal agricultural soil, for rehabilitation and pasture planning.
What this report foundExperimental studies tested ways to alleviate compaction on mine soils by combining mechanical treatment with organic material.
R1500,00
Experimental studies tested ways to alleviate compaction on mine soils by combining mechanical treatment with organic material. Survival of 16 pasture species was recorded on mechanically ameliorated compacted soil, dry matter and leaf area were measured for tall fescue and cocksfoot at different levels of organic material, and soil fertility, bulk density and root biomass were tracked under irrigated and dryland grass.
