Laboratory Manager Chris Walne has written in the Internationally published trade magazine Bullion Bulletin which gives information insights for the bullion business.

His article “Platinum Group Metals in Gold and How to Detect Them” in Volume 6, Issue 3 explores suitable methods of analysis for checking for platinum group metals in refined gold.  Using his extensive knowledge gained over 31 years, he explains the recommended methods, their limitations, and the preferred technique of choice for us here in the Lab at the GCAO.

Chris says “The magazine is published for the Asian gold markets, in particular India which has a massive gold bullion market but lacks certain expertise in the analysis of precious metals. Many delegates from bullion dealers and refiners who publish in the Bullion Bulletin attend the London Bullion Market Association assaying and refining conferences. I have presented papers on fire assay and XRF in the past there, so the Editors asked me to write a paper on the analysis of PGM’s in high grade gold, and previously in 2014 on our work at the Assay Office.”

A visit to the Lab is included in our tours of the Assay Office – for info, and to book, contact Dave Merry.
