Two South African papers dealt with mine waters, Godfrey Madzivire of the University of Western Cape on the removal of sulphate from mine water using fly ash, and Lesego Moitsheki of Sasol Technology on the effect of free lime content on high pH and scaling of ash transport water.

The session finished with coffee, before the delegates dispersed to sample the delights of Cape Town.
