Metallurgical response is one of the biggest technical risk factors affecting the outcome of successful gold mining projects. Metallurgical testing is an industry accepted practice applied to address technical risk by generating hard-data reflective of the gold metallurgical behaviour of the metal bearing ores and various minerals. 

Determining the grade of gold in the orebody can be critical in establishing overall process options. Maximum gold recovery can normally be justified for high-grade deposits, even though this usually means relatively high capital and operating costs. Conversely, low-grade deposits must be treated at the lowest possible cost, even though this usually means sacrificing some gold recovery. Recently, combining new innovative approaches such as BIOX®, PLATSOL™, CIL/CIP modelling with traditional grinding, gravity, and separation and leaching techniques have resulted in producing the most economical and cost-effective gold ore bodies have ever seen.

For nearly 80 years in Canada, the mining sector has turned to SGS for our trusted gold expertise and experience in flowsheet development and bankable feasibility studies. Our demonstrated success in gold metallurgy has provided hundreds of companies and mines with effective flowsheets and practical technical solutions to gold processing problems. 

Our gold presentation will familiarize attendees with the main traditional as well as the innovative aspects involved in gold metallurgy, process and environmental risk mitigation all designed for the successful flowsheet development and establishment of the design criteria for gold ore bodies.  


Case Studies 

Case studies focused on test work from around the world will cover topics including:

  • Gold mineralogy
  • CIL/CIP Modelling
  • Cyanide Destruction


Who Should Attend? 

This session will be aimed to professionals involved in the mining sector including:

  • Geologists 
  • Mineralogists 
  • Process Engineers 
  • Metallurgists 
  • Miners 
  • Financiers 
  • Operators

Learning Outcomes 

Attendees will learn about the importance of sample selection and sample variability within the context of testwork program design and a summary of the key unit operations commonly subjected to metallurgical testing will be presented. Attendees will also learn how the data are used to achieve the main objective of the metallurgical testwork including process-flowsheet development and the establishment of the design criteria.


Presenter Bios 

Michael Gajo, B.Sc.

Senior Metallurgist

Michael Gajo is a Senior Metallurgist at SGS. He has 15 years’ experience in the minerals industry. He has a B.Sc. with a major in Chemistry and a minor in Economics. Since joining SGS in 2013, Michael has independently managed multiple budgets and results for several bench scale testwork projects primarily relating to gold and/or copper recovery. His metallurgical and mineral processing methods include gravity, flotation, pressure oxidation, cyanide leaching, acid leaching and cyanide destruction. He is responsible for data compilation and analysis, writing proposals and reports, and liaising with clients. He was instrumental during the commissioning of a 4L batch autoclave for the Vancouver Metallurgical group and preparing the maintenance and training programs related to autoclave use. He has extensive managerial experience and project experience for process development in gold processing, and hydrometallurgical studies. He has been involved in the design, construction and supervision of a number of pilot and production scale plants around the world.

Sarah Prout, Ph.D.

Manager, Metallurgy, Vancouver Operation

Sarah Prout is Manager, Metallurgy, Vancouver Operations. Prior to taking on the role, sarah served as Senior Mineralogist for 8 years. Sarah received her Ph.D. in mineralogy, petrography and economic geology in 2004 from Camborne School of Mines in the UK. Sarah has over a decade of geology and mineralogy experience. Sarah started her SGS career in January 2007 as a Mineralogist based in Lakefield and joined the SGS Canada’s Vancouver operations in 2010, as a Senior Mineralogist. While at SGS, she has developed extensive experience dealing with the management of process mineralogical projects using QEMSCAN, SEM, optical microscopy, EPMA and XRD analysis. With experience in dealing with global mining projects, she has worked on a wide range of deposits from base metals and iron ore to REE, U-Th and industrial minerals.
