Extraction of platinum group elements (PGE) is a major source of revenue in South Africa and the reserves represent about 75 per cent of world reserves. Most of the remaining Platinum Group Mineral (PGM) reserves are located ...

Secondary pebble milling is an attractive alternative to using ball-mills. It is of particular interest in older mines where tonnage has been reduced, spare mills are available and savings in operating cost are essential ...

South Africa is the world’s largest producer of platinum group elements (PGEs). Mining takes place in the Bushveld Complex, and recent statistics, (Mudd, 2010), showed that the UG2 reef is the main source of production, ...

In the absence of any significant legislation, paper recycling in South Africa has grown to a respectable recovery rate of 43% in 2008, driven mainly by the major paper manufacturers. Recently introduced legislation will ...

Production of platinum and associated metals is a major source of revenue for South Africa. Significant losses occur in the concentrating stage (10 to 15 per cent) and this research is focused on optimising platinum ...

The Fischer-Tropsch reaction technology is utilised in Sasol’s Coal-to-liquid plant to produce liquid fuels from low grade coal. There are several processes on the Coal-to-liquid plant that generate aqueous streams which ...

A number of interactive simulations are provided which explore some of the techniques presented in Applied Process Control – Essential Methods, and Applied Process Control – Efficient Problem Solving. The applications arise ...

South Africa is the largest supplier of platinum group metals (PGMs), which are mined from three reefs in the Bushveld Igneous Complex. About 60% of the world’s mined PGMs come from a single reef, the UG-2 reef (Mudd, ...

Polytetrafluoroethylene (Teflon®) is encountered in many environments – frying pans, clothing, osmotic distillation membranes, to name a few – yet the solubility and clustering behaviour of water with this material was ...

PCBs are persistent organic pollutants that have intentionally and unintentionally (through contamination) been added to mineral insulating oil to improve its insulating and cooling properties within electrical equipment. ...
