Heavy Mineral Concentrates for mineral exploration

micro XRF scan of heavy mineral concetrates

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 […]

Application of Spectral Instruments in Exploration, Discovery and Development of Mineral Deposits: A case history

The application of portable Raman spectroscopy (pRaman), portable XRF (pXRF), and micro-XRF (µXRF) proved invaluable during the exploration, delineation and development of the Sinclair Caesium Mine, Western Australia. This article provides an insight into the application of combined spectral technologies in the exploration for, and development of mineral deposits. An algorithm to estimate the lithium […]

Micro XRF: Resolving the question of resolution

Micro-XRF technology provides unique access to a scale of contextual chemistry that has previously not been widely utilised in industry. The instrument provides chemical information mapped at a multi-micron scale for samples up to 20cm in length (Fig 1). This has its advantages as it bridges the gap between the restricted small scale of Scanning […]

In collaboration with Portable Spectral Services, four companies have utilised μ-XRF technology to gain valuable information from Nickel sulphide samples. Preliminary data on these samples have been released as part of their ASX announcements in the last month to support findings from their respective deposits. Half core samples were analysed with the μ-XRF without any […]

We all love a cheeky bit of chocolate

We all love a cheeky bit of chocolate. No wonder, the botanical name for the cocoa tree is Theobroma cacao, which translates to “food of the gods.” As simple as it is to enjoy, it is one of most complex chemical mixtures known (over 1500 flavour components identified!).[1] Per capita for consumption, European’s take out […]

Power of the future: Uncovering the secrets of the NCA battery

Diagram of NCA Battery

Lithium-ion batteries come in a range of shapes, sizes and compositions, and these batteries are revolutionizing the way we produce, conserve, and use electricity. Since the late 1990s, advances in lithium-ion battery technology has been driven by the ever-increasing demand for mobile phones, laptops and other portable electronics. This technology has now been comprehensively applied […]
