Newcrest Mining and Gekko Systems have begun a three-year research and development program targeting improvements in energy efficiency, reduced operating costs, increased recovery and faster project implementation at existing and future planned projects for Newcrest.

Newcrest will benefit from the application of concepts to optimise crushing and grinding, utilising technologies and flow sheets that focus on gangue rejection, pre-concentration and liberation at coarse grind size. Important studies and work are being undertaken to support the metallurgy teams with a particular focus at the Cadia, Telfer, Hidden Valley and Bonikro operations.

The collaboration will also identify areas for improvement in the recovery of gravity amenable gold at the Cadia Valley operations, with the efforts focussed on both primary gravity circuit and secondary treatment.

This alliance will also review the introduction of gangue rejection methods at the Telfer mine. The ore is described as having a ‘brick and mortar’ structure due to the valuable minerals present within the more friable ‘mortar’ component of the matrix, providing the potential to separate waste from the valuable mineral by size, density and competency. This matrix has the potential to allow rejection of a significant portion of the ore for very little loss of valuable mineral using gravity methods.

Long-term strategic relationships between gold processing specialists such as Gekko and operators such as Newcrest Mining allow for high quality data-based site performance analysis. According to Paul Griffin, Metallurgy Manager, Newcrest Mining, using a specialist collaborative resource such as Gekko will provide significant insight into opportunities for improved operation at a number of Newcrest mine sites.

Benefits of long-term collaboration agreements:

  • Creates sustained change through long-term planning and effective implementation
  • Continuity of relationship and knowledge sharing
  • Work outside of specific project scopes
  • Focus on projects without operational distraction
  • Client has continual benefit of contractors’ areas of expertise
  • Ability to convert innovative ideas and concepts into more efficient processing
