Application of Earth ion Exchange Technology for Conversion of Ro Brine From Tutuka/new Denmark Into Saleable Products
Pilot trial on single stage reverse osmosis brine at a Mpumalanga power station treating acid drainage from a neighbouring colliery, with projections for the planned second stage.
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.

Experimental studies tested ways to alleviate compaction on mine soils by combining mechanical treatment with organic material. Survival of 16 pasture species was recorded on mechanically ameliorated compacted soil, dry matter and leaf area were measured for tall fescue and cocksfoot at different levels of organic material, and soil fertility, bulk density and root biomass were tracked under irrigated and dryland grass.

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.

No surface geophysical method can map individual bords and pillars at the depths typical of the Witbank coalfield, a limit the review attributed to physics rather than to technology, since the targets are small relative to their depth and conductive layers often lie above the seam. Borehole laser scanning remains the workable option, with sonar suited to flooded workings.
