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 […]
Field identification of mineral phases within LCT pegmatite systems has been made simple with the handheld Bruker BRAVO Raman with duo laser excitation (Figure 1). Figure 1. Bruker’s handheld BRAVO Raman What is Raman spectroscopy? Raman is a form of vibrational spectroscopy that generates a spectrum by directing a monochromatic light from a laser onto […]
Historically, detecting low levels of gold in the field with pXRF has been a challenging process with no truly accessible methodologies available. Portable ppb Pty Ltd’s DetectORE™ technology brings compatibility for the detection of low-level gold by pXRF analysis. DetectORE™ is a patented technology to detect gold at low level concertation’s (<20 ppb) using a portable XRF such as […]
Introduction The dominance of China in the rare earths industry has forced the USA, Russia, European Union, Japan, Australia, and other counties to formulate policies and implement strategies to ensure security and sustainability of rare earth elements (REE) to reduce dependency on Chinese supplies. Notably, in 2020 the European Union’s report on critical raw materials […]
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 […]
As we all know, no two deposits are exactly alike. Each one comes with its own unique characteristics and challenges. Defining the geochemistry of a deposit is a critical step that often requires a significant amount of time and expense. In the past decade, the use of portable XRF (pXRF) instruments to provide rapid in-field […]
How to get the most from your data with the help of Certified Reference Material Certified Reference Materials (CRM’s) are of great assistance with portable XRF data Quality Assurance and Quality Control (QAQC). CRM’s provide a check for elemental concentrations, in addition to checking for low level contamination of the XRF instrument. A question Portable […]
An important part of using a portable XRF (pXRF) is the correct licencing of the instrument in the state where it is being used. This ensures that the instruments are being used safely and responsibly and can vary from state to state within Australia.
