Optimal design of a secondary milling circuit for treating chromite-rich UG-2 platinum ores.
(2011)
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 ...
The optimisation of pebble grinding.
(2013)
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 ...
An investigation into the effects of UG2 Ore variability on froth flotation.
(2013)
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, ...
Neural network modelling and prediction of the flotation deinking behaviour of complex recycled paper mixes.
(2011)
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 ...
The development of an experimental technique for UG-2 ore flotation.
(2013)
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 ...
Investigation into the effect of stripped gas liquor on the anaerobic digestion of Fischer-Tropsch reaction water.
(2014)
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 ...
Applied process control : simulations.
(2015-12-09)
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 ...
An investigation of froth effects in scavenging flotation of platinum from UG-2 ore.
(2013)
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, ...
Monte Carlo simulations of systems of light alcohols + water + n-dodecane and water solubility and structures in polytetrafluoroethylene.
(2011)
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 ...
Investigation of the effects of polychlorinated biphenyl (PCB) dechlorination on the natural inhibitors and oxidation stability of uninhibited naphthenic based mineral oils.
(2010)
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. ...
