Raw Materials Research

Proven Research Capability

As global demand rises, the need to develop and implement more efficient processing techniques becomes increasingly important.

The challenges for the industry are that the quality of raw materials is declining and high quality ores for blending are becoming harder to source at affordable prices.

Dedicated research into raw materials processing is provided by the Materials Processing Institute. The Institute has a long established evaluation capability to test and develop at pilot scale, ore composites and agglomerates for iron making and ferro-alloy production; as well as beneficiation and recycling of process residual materials.

Raw Materials Research

The Institute's raw materials research is focussed on the development of pre-treatment and agglomeration technologies. This research enables efficient material upgrading processes for maximum value in use and optimal efficiency of processing for ores, raw materials and process reverts.

Benefits of Pre-treatment and Agglomeration Process Research

  • Evaluation of a wide range of ore and material blends matched to sinter plant operations
  • Optimisation of ore and material blends to enhance production and value in use
  • Understanding the productivity and fuel rates of blends to be used during production
  • Support in defining sinter and pellet plant operating process controls
  • Raw material and product characterisation
    • Strength
    • Degradation
    • Reducibility
    • Porosity
    • Morphology
  • Environmental impact evaluation
  • Re-use and processing of residual materials
