Flowsheet Development

An efficient, optimized flowsheet is the cornerstone of your metallurgical extraction project. Our flowsheet design activities yield the economic, environmental and efficiency parameters of your metallurgy project – throughput, recovery and product grade. Bankable SGS flowsheets also prove the viability of your project to financers and stakeholders from the pre-feasibility stage to full operation. SGS has earned a global reputation as a proven leader in the development of transparent, bankable flowsheets for a wide range of mineral and metal extraction operations.

Our flowsheets allow you to:

  • Provide bankable milestones to maximize financing options
  • Quantify and minimize the effect of ore variability
  • Generate higher value from your ore by optimizing operations that control throughput and recovery
  • Minimize risk associated with process changes
  • Reduce environmental costs through appropriate design features

Whether your project is in the pre-feasibility or feasibility stage, our process design experts have the expertise and technology to complete a wide range of scoping metallurgical tests that accurately characterize your ore and establish the processing steps in your operation. We use the findings from these industry standard metallurgical tests to develop a conceptual flowsheet for your operation. The performance of the flowsheet is then confirmed and fine-tuned for optimal operation in a pilot plant on a “mini-mine” scale in an SGS laboratory.

In existing operations, changes in ore-type, recovery targets, technology and equipment, or environmental regulations may mean that existing flowsheets must be altered or even significantly revised. We can help you to revise your flowsheet and reoptimize your plant performance to significantly reduce your technical and financial risk.

Our experts work with you at every stage of your flowsheet development, and your input on timing, anticipated project scope and financial requirements allows us to develop the process that will help you to reach your project goals. Take advantage of our sweeping depth and breadth of expertise to reduce key elements of your technical risk.
