Past Projects Include:

 
  • Flow behaviour and dewatering characterisation of oil sands to establish pumping requirements, operating limits and thickening characteristics.
  • Rheology of red mud tailings for dry stacking implementation and operation. Evaluation of alternative tailings treatment and disposal options.
  • Nickel laterite HPAL feed rheological characterisation for maximising feed concentration without compromising autoclave efficiency or pumping and thickening efficiency. Provision of rheological data for dewatering, pumping, pipeline design, agitation, autoclave design and tailings disposal.
  • Assessment of the effect of temperature, concentration and shear history on the rheology of nickel laterite slurries.
  • Rheology of various mineral tailings for paste backfill applications (over 30 operations). Determination of yield stress and viscous behaviour as a function of solids content and cement addition rate.
  • Fly ash neutralisation and rheology. Effect of pipeline shut down on rheology. Shear rheology, dewatering characterisation and thickener modelling for fly ash disposal at elevated solids loadings.
  • Flocculant assessment for optimal rheological, sedimentation and filtration characteristics.
  • Shear rheology of Ni laterite feed and tailings, dewatering characterisation and thickener modelling for a definitive feasibility study.
  • Shear rheology, dewatering characterisation and thickener modelling of copper tailings for enhanced water recovery.
  • Investigation into factors affecting bauxite ore long distance pipeline flow and processing characteristics.
  • Rheology and surface chemistry testwork for recommendation and implementation of a suitable chemical regime for optimisation of thickening of a coal/clay slurry.
  • Dewatering characterisation and modelling for evaluation of thickened clay technology.
  • Rheology of polymer additive for fire-fighting water.
  • Rheology and dewatering characterisation of neutralisation residue for in-pit disposal investigations. Modelling of pit filling rates and consolidation performance.
  • Rheology of sewage sludges for analysis of digestion and heat transfer options and pumping requirements.
  • Expert advice and witness on court cases.
  • Effect of surface chemistry on the processing and dewatering characteristics of ores and tailings.
  • Investigation into the effects of clay content and chemistry, particle size and shear history on the rheology of mineral sands tailings.
