Description
The Carbon Farming Model for Rehabilitated Coal Mine Land assessed the potential to transform rehabilitated coal mine land into productive landscapes that support biomass production, renewable energy generation, soil regeneration, carbon sequestration and community enterprise development. The project demonstrated that rehabilitated mine land can successfully support high-biomass species, particularly when supported by organic amendments such as biochar and digestate. It provides a practical and scalable approach for turning post-mining land from a rehabilitation liability into an environmental, economic and social asset.

Tonnage estimates for the remaining low phosphorus resource could not be produced, because the phosphorus analyses supplied by mining companies did not state what had been measured. Distribution trends were still mapped. Coal at or below 0.010 per cent phosphorus is widespread in the Witbank Coalfield, restricted to the far northwestern Highveld, and follows a northwest to southeast band in eastern Ermelo.
Cost Evaluation of Different Medium Solids for Air Dense Medium Fluidized Bed Coal Separation
2017
University laboratory work on air fluidised bed separation, testing pyrrhotite, blast furnace slag, silica sand and coal discards against magnetite, for engineers considering waterless coal washing.
What this report foundMagnetite and pyrrhotite each gave the most uniform and stable fluidised bed densities, with bed density variation under 0.7 per cent.

Magnetite and pyrrhotite each gave the most uniform and stable fluidised bed densities, with bed density variation under 0.7 per cent. A pyrrhotite and magnetite blend at a weight ratio of 40:60 beat magnetite alone, producing a product of 14.50% ash and 27.30 MJ/kg from a feed of 39.27% ash and 18.76 MJ/kg.
