  3. Ore Characterisation The accurate prediction of an ore’s 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 ore’s properties and processing potential.

  4. 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.

  5. 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.

  6. contd… • 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

  7. 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.
