Bureau Veritas MineralsMineralogy and Petrography Automated Mineralogy by QEMSCAN and MLA for the Mining Industry
MINERALS
Mineralogical studies are critical to successful geological exploration and the processing of ores. We offer a full range of packages including: bulk mineralogical analysis (BMA), particle mineralogical analysis (PMA), trace mineral search (TMS), FieldScan (FS) using QEMSCAN, MLA Express and optical mineralogy for both thin and polished sections.

Bulk Mineral Analysis (BMA)This investigation is a one-dimensional linear analysis of point counting that provides a fast, basic study of mineral deportment.
■ Complete mineral composition and deportment ■ Element deportment ■ Mineral association ■ Mineral liberation ■ Mineral grain size
Particle Mineral Analysis (PMA) A two-dimensional mapping analysis that provides in-depth data for investigative purposes such as the flotation or leaching process.
■ Complete mineral composition ■ Elemental deportment ■ Mineral liberation and associations by size ■ Effect of primary grind on mineral liberation ■ Limiting grade recovery curves for the elements of interest
Trace Mineral Search (TMS) TMS is a refinement of the PMA scan but only measures a sub-population of the particles based on a backscattered electron intensity threshold value.
■ Target mineral (gold/silver/PGM) grain size ■ Target elemental distribution across bearing minerals ■ Mineral grain size distribution ■ Mineral liberation and association ■ Mineral locking characteristics ■ Mineral liberation by free surface

Diagnosis of Metallurgical PerformancesUsing the combined methods of QEMSCAN/MLA analysis, to determine the sources that caused contaminations in the final concentrates and the losses of target metals into the tailings in plant operations or metallurgical tests.
■ Efficiency of primary grind and regrinding on the target mineral liberations ■ The quality of final concentrates ■ Status of the target minerals lost into the tailings ■ Target mineral recovery by process streams, by mineral association class
and by particle size ■ Evaluation of potential improvement in the concentrate quality and metal
recovery of plant operations or metallurgical test work
