Application of EARTH Ion Exchange Technology to Process RO (Hipro) Brine from eWRP
Pilot trial on brine from a working water reclamation plant on the Mpumalanga coalfield, the first of four studies testing ion exchange on coal mine liquors.
Ion exchange applied to brine from a three stage reverse osmosis plant at eMalahleni converted the brine entirely into saleable fertiliser and explosives feedstock, and recovered close to half of the water the reverse osmosis stage leaves behind. On this basis the existing brine pond and the two planned for the plant expansion would not be needed.

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.
An Environmental Management Accounting Model for the South African Mining Industry
2008
Doctoral work comparing environmental cost practice at four South African mines and building a model from it, for environmental managers and finance staff in mining companies.

Conventional cost accounting at the mines studied could not report on physical structure or materials flow, so environmental costs such as water, energy and consumables stayed hidden and chances to cut them were lost. Four case studies across different commodities and mining methods showed the same limitations. An environmental management accounting model is proposed to identify and allocate those costs.
A manual for authorisation of pitlakes as a closure option for South African coal mines
2021
A practical guide for coal mines and their consultants, built on earlier water research on pitlake viability, with South African examples from the Highveld, Waterberg and KwaZulu-Natal coal fields.

R1500,00
Sets out the authorisation route for leaving a pitlake as a closure landform, covering water use licensing, environmental authorisation and the wider legislative process. There is no single application that grants approval, and the route is long and partly duplicated, so several applications are required.
