Session Details

Automated mineralogy (AM) technologies have been a critical tool for the past 20 years to help develop, support and troubleshoot metallurgical flowsheet development. QEMSCAN is but one of these technologies on the market that can provide quantitative modal mineralogy, grain size, liberation, association and exposure data for various commodities from base metals, to industrial minerals and precious metals.

Mineralogy can be carried out on composites and variability samples to understand up front where the payable metals occur in terms of recoverable or non-recoverable minerals via flotation or gravity or leaching; also, the size of these minerals in terms of how far the sample has to be ground in order for a particular mineral/s to be liberated or its exposure in terms of flotation or leaching.  Samples can also be taken from various points on the flowsheet during development to troubleshoot regrind sizes, unexpected abundances of the payable minerals within the various tailing products or gangue identification if the concentrate is not hitting the expected grade and/or recovery or deleterious/payable minerals (elements) within the final concentrate. 

Examples will be shown from a copper porphyry, polymetallic and gold flowsheets of where automated mineralogy can be shown to provide upfront information on the feed and where it can be used to identify problems.


Learning Outcomes

1. General introduction to automated mineralogy. 

2. Where automated process mineralogy can be used to develop a flowsheet. 

3. Why automated process mineralogy can provide value. 


About the Presenter

Sarah Prout (Ph.D.) is a Senior Mineralogist, Vancouver Operations for SGS Canada based in Vancouver, BC. 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.
