Application of EARTH Ion Exchange Technology to Process RO (Hipro) Brine from eWRP
Pilot trial on brine from a working water reclamation plant on the Mpumalanga coalfield, the first of four studies testing ion exchange on coal mine liquors.
Ion exchange applied to brine from a three stage reverse osmosis plant at eMalahleni converted the brine entirely into saleable fertiliser and explosives feedstock, and recovered close to half of the water the reverse osmosis stage leaves behind. On this basis the existing brine pond and the two planned for the plant expansion would not be needed.

R1500,00
Sets out good practice for planning, implementing, monitoring and adaptively managing land rehabilitation at surface coal mines, with generic rehabilitation objectives, implementation actions and suggested relinquishment criteria for each component. It updates guidance first issued in 1981 and revised in 2007, reflecting later changes to South African rehabilitation legislation.

Practical guidance for opencast operations covers early detection with low cost thermal cameras, prevention, and the treatment methods in current use: water sprays and cannons, sand cladding of highwalls and stockpiles, removal of burning coal by dragline, tipping into water ponds and the treatment of sinkhole areas. A three month full scale trial of sprayed fly ash as an antioxidant is reported.
