Download our HMC Brochure Australia is the home to the world’s largest heavy mineral deposits containing titanium, zircon, and rare earth elements as well as heavy mineral concentrates (HMC) extracted from surficial sediments in alluvial, fluvial, glacial and wind environments. Early-stage exploration and processing of heavy minerals utilises techniques such as gravity and magnetic separation […]

What is your money really worth? | Micro-XRF

micro-XRF elemental map of coins

Over the course of Australian history the coins used in circulation have changed multiple times from hole-punched Spanish coins to Dutch guilders, English pennies and now the Australian Dollar. One of the issues we have faced during these transitions is when the material value of the coin outweighs its value as a currency. What is […]
