Determination of the Impact of Coal Mine Water Irrigation on Groundwater Resources
Groundwater investigation behind mine water irrigation in the Mpumalanga coalfields, with hydraulic testing, leaching studies and site selection and monitoring guidance for mines and regulators.
by P.D. Vermeulen, B.H. Usher and G.J. van Tonder | April 2007
Monitoring and geochemical modelling at five pilot sites, on undisturbed soils and on opencast spoils, showed that most soils held a large share of the applied salt in the upper unsaturated zone and that salinity built up slowly. Leachate volumes, leachate quality and aquifer mixing ratios were quantified. Irrigation is recommended on alternating pivots and for no longer than ten years in one area.

2012
Global, regional and South African market analysis of ion exchange resins as applied to mine waste brine, including a United States pilot plant, for technology and investment decisions.
What this report foundIon exchange was assessed as a treatment route for brine arising from mine water cleaning, from a market rather than a plant performance standpoint.

Ion exchange was assessed as a treatment route for brine arising from mine water cleaning, from a market rather than a plant performance standpoint. World demand for ion exchange resins was expected to pass 535 million dollars by 2015, driven by urbanisation, pollution and shortages of clean water in developing regions.
