Small Scale Coal Mining Guidelines
Plain language manual for newcomers to the coal industry, written for historically disadvantaged entrants with limited technical background and no route into the ownership and permitting process.
Sets out the steps to establish a small scale coal mine in South Africa, from mineral rights and regulatory approvals through finance, mining and processing choices, marketing, and environmental management and closure. The information a new entrant needs sits in many separate places, so the guideline draws it together from practitioners rather than from any single published source.

Coal can feed products well beyond combustion. The study sets out routes to rare earth elements held in particular seams, building materials made with carbon fibre and carbon char, coal foam and graphene composites, carbon black and activated carbon, including a coal derived activated carbon reported to hold four times the gas of compressed natural gas at lower pressure.

Dense medium cyclones on the fine coal fraction lifted product yield well above the spiral circuit they were compared against and gave closer control of product quality. Cut point density control proved the hardest part of running the plant, medium properties being critical. Magnetic separator capacity had to match the duty, and a basement was needed to contain and recover medium spillage.
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.
