LEICESTER, England – Efforts are under way to develop a handheld mineral analyzer for mining applications – the first of its kind. Allowing for rapid mineral identification and quantification in the field through a combination of x-ray diffraction (XRD) and x-ray fluorescence (XRF), the instrument will be created through a collaborative project between the University of Leicester’s Space Research Center (SRC) and Bruker Elemental. The addition of XRD capability is an improvement upon current XRF instruments, which sell thousands of units globally each year. The instrument is expected to weigh 1.5 kg and be able to analyze mining samples for mineral content within one to two minutes. There is no need for sample preparation – an unprecedented feature of XRD equipment. A rock specimen mounted for analysis. Photo courtesy of Dr. Graeme M.

Next, the project will focus on developing and testing the methodology using samples that are representative of real-world problems encountered in mining, such as determining the relative amounts of iron oxide materials in ore samples. The SRC and Bruker will develop a handheld prototype to demonstrate the technology’s efficiency in the field.
