Treatment of acid mine drainage for reuse in irrigation
Mintek | October 2022

Description
Mintek’s cloSURETM technology has been specifically developed for mine sites post-closure and would be suitable for implementation at sites with low or unpredictable flow, at remote locations and in areas lacking services/infrastructure. The two- stage process, consisting of a bioreduction followed by a bio-oxidation step, is intended to produce water that is fit for re-use, specifically in irrigated agriculture. The objective is to reduce the cost of mine water treatment, and to create the opportunity for revenue generation through the re-use of the water to produce crops, and possibly through the production of a bio-sulphur product.

Stockpiling degraded every soil property measured across four Witbank area mines. Clay content of topsoil and subsoil rose by 50 to 60 per cent, surface bulk density increased from stockpiling through to rehabilitation, and effective depth on rehabilitated areas was under 17 cm in most cases. Topsoil organic carbon fell by almost half and microbial species numbers dropped in the stockpiles.

No surface geophysical method can map individual bords and pillars at the depths typical of the Witbank coalfield, a limit the review attributed to physics rather than to technology, since the targets are small relative to their depth and conductive layers often lie above the seam. Borehole laser scanning remains the workable option, with sonar suited to flooded workings.
