Treatment of acid mine drainage for reuse in irrigation
Mintek | October 2022
R1500,00
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.

R1500,00
Microgravity, resistivity based methods including self potential, and time domain electromagnetics are identified as able to detect and delineate shallow old workings, with controlled source audio magnetotellurics useful below about 30 metres. How well each performs depends on target depth, the material filling the void and the overburden, and has never been quantified. Field trials were planned to close that gap.
Guideline for Mine Closure Relinquishment Criteria
2023
Review of closure and relinquishment law in Australia, Canada and South Africa, with four mechanisms for reaching agreement compared. For closure planners and regulators.
What this report foundRelinquishment criteria follow from the agreed post-mining land use. The land use is the goal and the criteria measure whether it has been reached.

Relinquishment criteria follow from the agreed post-mining land use. The land use is the goal and the criteria measure whether it has been reached. The guideline sets out a framework for approving those criteria at each mining phase, from the initial environmental management plan through to decommissioning, and compares South African practice with Australian, Canadian and international guidance.

R1500,00
Mapping abandoned, inaccessible bord and pillar workings comes down to two options: borehole deployed laser or sonar scanning, or sensors carried in by unmanned vehicles. Drone mounted laser scanning for air filled voids and sonar carried by small submersibles for flooded workings were judged the most promising, but intrinsic safety, deployment and the risk of losing equipment still favour borehole methods for occasional use.
