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.
Upgrading of coal fines with a Centrifugal Concentrator
Bench and pilot testing of four centrifugal concentrator models on fine coal from two collieries, with operating variables that resisted correlation flagged for further work. For plant metallurgists.
What this report foundFour centrifugal concentrators all cut ash in fine coal, with desliming the decisive step.
R1500,00
Four centrifugal concentrators all cut ash in fine coal, with desliming the decisive step. The best unit took ash from 35.2% to 18.47% and sulphur from 0.68% to 0.36% in a single stage, raising calorific value from 23.78 to 26.16 MJ/kg. Pilot work reached 19% ash on thickener underflow and reconstituted spiral feed.
More Effective Use of Disposable Dust masks
Underground field trials, laboratory seal tests and operator questionnaires at two collieries, covering mask selection, fit, issue records and service time. For ventilation and occupational hygiene staff.

Dust masks worn by load haul dump operators passed 200 mg of filter loading in an average of 1.7 hours, and continuous miner, shuttle car and roofbolt operators reached the same point within two to five hours. Every mask failed laboratory fit testing. An eight hour service life is too long.
