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

What this report found

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.

Coal Washability Using Coal Petrography

2019

Summary of postgraduate work validating washability prediction for southern African coals by image analysis and tomography, written for geologists, metallurgists and mining engineers valuing a deposit.

What this report foundA single float sink test destroys the sample and gives one deterministic answer, so it cannot show how washability changes with particle size distribution.

What this report found

A single float sink test destroys the sample and gives one deterministic answer, so it cannot show how washability changes with particle size distribution. Simulating washability from petrographic images and tomography allows many size distributions to be tested statistically from one sample. Running simulation alongside float sink work during exploration lets the prediction error of each be compared.

What this report found

Ion exchange converted reverse osmosis brine from a power station treating colliery water and cooling tower blowdown into fertiliser and explosives salts, with no liquid effluent left to dispose of. Part of the water rejected by the reverse osmosis stage was also recovered as potable water. Brine is currently used for dust suppression and stored underground.

Wetlands Inventory of Upper Olifants River Catchment

What this report found

A digital wetland map and linked database were compiled for the Upper Olifants River Catchment from existing literature, existing wetland layers and aerial photography. Wetlands cover about 2 147 km2, some 14 per cent of the 15 158 km2 catchment. The wetland layer is about 70 per cent accurate and its attributes about 60 per cent, so it suits baseline screening rather than site assessment.
