Description
The Biological Treatment of Brines assessed the use of Mintek’s cloSURE® biological sulphate reduction process to treat hypersaline reverse osmosis brine generated by the eMalahleni Water Reclamation Plant. The study demonstrated, at bench scale, that biological sulphate reduction can be sustained under high-salinity brine conditions, offering a potential alternative to evaporation ponds for managing coal mine brine waste. It provides proof of concept and design parameters for future pilot-scale testing, while also highlighting the need for further work on hydrogen sulphide management, calcium removal and potential value recovery from treated brines.

Mines already provide substantial training and their junior managers were found motivated and committed, yet development at this level remains problematic. Gaps sat in commercial exposure, financial and accounting skills, industrial relations, quality standards, administration and project management. The report sets out the attributes to screen for at appointment and a framework that makes candidates responsible for their own development.

A rating and ranking system was applied to South African coalfields and, separately, to the coal bearing countries elsewhere in the Southern African Development Community. The Waterberg ranked highest in South Africa and is the coalfield most worth detailed investigation as Witbank output declines. Botswana ranked highest among the other member states on contained resources and exploitation potential.
