Treatment of acid mine drainage for reuse in irrigation

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.
