QEMSCAN®
QEMSCAN® technology can be used to generate a quantitative picture of sample mineralogy for use in development and in industry, allowing Hazen to aid its clients in characterizing a deposit, designing a milling process, troubleshooting refractory leach behavior, or addressing other commercial project concerns.
QEMSCAN® uses advanced electron beam technology and combines this with high-resolution backscattered electron (BSE) imaging and four state-of-the-art liquid nitrogen-free energy dispersive spectrometers (EDS). The components are then integrated using electronic control systems and the unique iDiscover software suite to provide a comprehensive tool capable of identifying most ore- and rock-forming minerals on a micro-scale in just milliseconds.
The EDS and BSE data are collected at user-defined stepping intervals across the sample (typically 1 – 30 micrometers). The analyses at each point are correlated with a library of mineral/phase identifications such that each data point is mapped as a specific mineral or phase. The output of the analysis is a false-colored image with associated quantifiable data. The iDiscover software not only controls the operation of the hardware but also analyzes the data generated to provide information about the chemical and mineral composition of the sample, as well as the textures, mineral abundances, mineral associations, grain sizes, liberation characteristics, surface exposures, and shapes through the analysis of digital mineral maps.
QEMSCAN® has the ability to handle a wide range of sample types, usually set in epoxy, as blocks or thin sections, and even set on conductive tape. It can be used for analyzing almost anything from core samples, offcuts, and rock chips to soil, manufactured products, and dust.
