DyVar Pilot Test Report
Batch pilot trial of a salt concentration unit on saline coal mine effluent at the eMalahleni reclamation plant, for mines weighing brine treatment and salt recovery.
A pilot brine concentrator treated Stage 3 reject effluent from a mine water reclamation plant, raising total dissolved solids from 24 g/L to 154 g/L at 88 per cent water recovery. The condensate met the national potable water specification. A separate run concentrated brine from 76 g/L to 145 g/L, solid salts were precipitated, and no scaling or fouling was seen.

Monitoring and geochemical modelling at five pilot sites, on undisturbed soils and on opencast spoils, showed that most soils held a large share of the applied salt in the upper unsaturated zone and that salinity built up slowly. Leachate volumes, leachate quality and aquifer mixing ratios were quantified. Irrigation is recommended on alternating pivots and for no longer than ten years in one area.
Development of a Horizontal Winnower for the Beneficiation of Fine Coal
Proof of concept work on dry beneficiation of minus 6 mm coal, combining airflow modelling and simulation with a laboratory winnowing box, for plants short of process water.

Horizontal air winnowing separated fine coal by particle size and density in laboratory experiments, supported by equation of motion modelling and computational fluid dynamics. Modelling indicated that a chamber 0.6 m high and 1 m long is sufficient to displace any minus 6 mm particle at air velocities of 10 to 30 m/s.

A regional monitoring programme was found to be viable and is proposed as a public private partnership covering air emissions, air quality and energy efficiency on the Mpumalanga Highveld. The assessment concluded that the worst health impacts fall on residential areas, driven by inefficient coal burning for heating and by housing sited close to large industry.
