An Environmental Management Accounting Model for the South African Mining Industry
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.
by Maryna Möhr-Swart | February 2008
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.

Existing thermal imagery of the Witbank coalfield was traced to its holders and assessed for format, quality, resolution and coverage, then brought into one geographic information system with supporting metadata. Satellite thermal bands give a regional picture only; detailed mapping of coal fires or acid drainage discharge needs high resolution aerial surveys.
TRI-FLO™ Tests Conducted at South Witbank Coal Mine
2003
Trial of an imported dense medium separator installed in a fine coal pilot plant at a Witbank mine, for plant designers weighing alternatives to cyclones.
What this report foundThe separator handled fine coal and produced a 28 MJ/kg product, but its measured separation efficiency was lower than that of conventional dense medium...

The separator handled fine coal and produced a 28 MJ/kg product, but its measured separation efficiency was lower than that of conventional dense medium cyclones and it was harder to operate. Two efficiency tests produced no evidence that the unit outperforms cyclones on fine coal, so cyclones were recommended when the plant was rebuilt at its next site.
