Process Design & Engineering Process Design & Engineering

World class process development, finding technically and economically robust process solutions for mining projects.

Engineering Studies

Core’s engineering group conducts scoping, pre-feasibility and feasibility process engineering studies.  As a specialist process engineering group, our engineers provide expert guidance for a wide range of clients on the metallurgical development of their projects.  As part of this development, Core can generate:

• Process flow diagrams and costed equipment lists

• Detailed mass and energy balances for your process using Excel, METSIM or HSC Chemistry

• Specify, size and cost all the process equipment in your process flowsheet using our in-house equipment list and vendor supplied quotes

• Develop process operating costs including detailed power schedules, reagents and consumables list and plant labour schedule.

• Identify Life of Mine operating strategies, built around geometallurgical data for your project

Clients come to us to solve a variety of process problems:

•  Optimise your process flowsheet to minimise risk, operating & capital costs.
•  Develop a variety of processing options for your resource, outlining the drivers for each.

•  Evaluate competing flowsheet options, and identify a preferred flowsheet for the resource.
•  Identify parameters that are critical to your process and develop strategies to address these issues.
•  Improve grade or recovery by enhancing existing processes or development of alternative processes that improve a project’s economics.

Process Engineering


  • Flowsheet development based on geometallurgical data, metallurgical testwork, process modelling and best practices.
  • Metallurgical accounting & mass balancing.
  • Technical and economic analysis and evaluation of process options.
  • Process modelling with METSIM and HSC.
  • Selection and sizing of all metallurgical equipment.

  • Development of design criteria documentation.
  • Development of operational control philosophies.
  • Proposal and evaluation of alternative process options and selection at the conceptual, pre-feasibility and feasibility study phases.
  • Development of new processes or improving existing processes to achieve higher productivity levels and higher recoveries.
  • Project management services, typically as a client representative post flowsheet development.
  • Development, construction and management of pilot plant facilities and programmes.
  • On site processing plant commissioning services.
  • On site processing plant optimisation services.


Core’s process engineering work incorporates all factors relevant to the project including market, metallurgical, economic, environmental, geographical and regulatory drivers.
