• Ore Characterisation
• The accurate prediction of an ores downstream
  processing performance is critical to resource
  evaluation and development decisions. Significant
  cost and productivity benefits can be realised
  through the early determination of an ores
  properties and processing potential.

• Beneficiation
• Alternative hematite/geothite ore sources such as
  Marra Mamba and Channel Iron Deposits demand more
  effective beneficiation strategies that can
  accommodate changing ore blends and remove gangue
  components while minimising loss of iron units.
  Magnetite ores also require beneficiation before
  further processing.

• AgglomerationOur agglomeration research is
  proving instrumental in helping companies
  throughout the world improve product quality and
  reduce environmental emissions. Together with
  industry, we are optimizing existing practices
  and conducting trials ranging from laboratory to
  pilot-scale on new ores and ore blends.

• More specifically, this involves
• Optimising of granulation
• Analysing and predicting sintering properties of
  new ore types and blends
• Determining optimum fineness of pellet feed ores
• Optimising pelletising performance, including
  balling and induration
• Developing alternative agglomeration processes
• Assessing blast furnace performance
  characteristics of agglomerates
• Developing strategies for minimising dust and
  gaseous emissions
• Developing simulators (called Siro-Indur) for
  straight-grate and grate-kiln indurators
• Investigating alternative fuels to reduce
  environmental emissions
• Utilising alternative sources of iron units,
  including waste mater

• Pilot-Scale Facilities
• Our laboratories in the Queensland Centre for
  Advanced Technologies (QCAT) offer a range of
  world-class facilities for batch and continuous
  pilotscale testing of iron ore processing
  operations. Amongst these is our state-of-the-art
  pilot-scale sinter rig. The sinter rig is well
  instrumented, featuring automatic data logging
  via computer control and monitoring of gas and
  particulate emissions, including CO, CO2, NOx and
  SOx.
