AUTOMATED MINERALOGY EQUIPMENT AT ACTLABS

The Applied Mineralogy department employs the latest analytical instruments for automated mineralogy investigations.

QEMSCAN (Quantitative Evaluation of Minerals by Scanning electron microscopy) is an automated scanning electron microscopy system, which performs non-destructive, rapid EDS micro-analysis used for generating mineralogical, and metallurgical data. The QEMSCAN at Actlabs uses an FEG (Field Emission Gun) filament, which increases the image resolution. The spectra are collected with two Bruker 5030D EDS detectors. The spectra are subsequently identified by comparing their distinctive energy dispersive X-ray spectra with a mineral identification library known as the Species Identification Protocol (SIP). Qemscan analysis at Actlabs is tailored to best fit our clients’ needs; including customizing the SIP file, to better fit the nature of the samples which improves reliability and the quality of your mineralogical data.

Mineral Liberation Analyzer (MLA) is an automated SEMsystem, which identifies and quantifies the minerals based on their BSE level and compares the collected spectrum shape with a mineral database.

The MLA 650 F is a fast, automated, analyzer which provides reliable particle and textural data, used by mineralogists, geologists and metallurgists for mine feasibility and ore characterization studies as well as ore processing optimization. MLA analysis is capable of producing particle data specifically for liberation and association studies. The FEG-MLA is the best instrument for locating and identifyinggold and platinum group mineralogy.

X-ray diffraction (XRD) is a well-established analytical technique, used in mining and exploration, materials testing, life sciences, pharmaceutical, and other industries, for the identification and/or quantification of crystalline phases. Actlabs uses X’Pert Pro diffractometer, equipped with a Cu X-ray source and an X’Pert High Score Plus software suite, and the International Centre for Diffraction Data PDF-4/Minerals mineral database. This allows us to provide identification and quantification (by Rietveld) of crystalline minerals, as well as quantification of amorphous content in soil and powdered whole rock samples, clay speciation analysis on the separated fine grain size fraction, cluster analysis on large sample sets, and GMP certified pharmaceutical testing on raw material, API, clinical material, and finished products.

For petrographical studies, polished thin sections can be studied using a transmitted/reflective microscope Olympus BX51 and also be analysed and mapped by QEMSCAN or MLA. Actlabs also offers Microprobe analysis as well as Laser Ablation ICP-MS services.
