P AGE 26 Applied Mineralogy and Geometallurgy Services Quantitative High Definition Mineralogical Analysis by MLA and QEMSCAN Applied Mineralogy is a discipline of mineralogy by which the unknowns and problems encountered during dif ferent mining steps can be approached and solved Applied Mineralogy can be used to characterise the ore body identify and quantify target minerals and their associations and reveal the liberation locking and grain size of the favoured phases The data provided by Applied Mineralogy is essential for ore characterization optimising recovery and mineral processing plans Geometallurgy is an integrated methodology and multidisciplinary field which aims to add value to a mineral deposit or resource while looking ahead at risk reduction improved decisionmaking and costef fective downstream activities eg development prefeasibility feasibility and production The objective of successful Geometallurgy is quality ore characterization and establishing links and relationships between geology mineralogy and processing characteristics For quantitative mineralogical analyses Actlabs is equipped with FEI Quanta 650F MLA and QEMSCAN 650F instruments they are stateof theart Scanning Electron Microscopes SEM with superior resolution and performance over typical SEM systems The Field Emission Gun source makes for significantly higher resolution analysis relative to regular MLA and QEMSCAN technology Actlabs Quanta 650F MLA and QEMSCAN 650F provide rapid automated nondestructive quantitative micro analysis used for integrated mineralogical and petrographical analyses Actlabs of fers mineralogical analysis of assay rejects drill core RC drilling chips plant samples and most other forms of ma nmade and natural materials MLA can be applied to precious metals Au Pt Pd Ag base metals Cu Ni Co Pb Mo Zn ferrous and no nferrous raw materials Fe Sn Mn W T a Nb U and REE mineral sands and graphite bearing rock Deliverable services for Geometallurgy and Applied Mineralogy Quantified Modal Mineralogy Analysis A rapid and ef ficient solution for identifying and quantifying the minerals present with detection limit of 01 The measureme nt can be done on both thin section and polished section Particle and Grain Data Analysis This type of analysis provides information on texture variations size distribution of the target minerals as well as locking and liberation characteristics for the ore minerals Theoretical graderecovery curve and association of the ore mineral with the gangue is al so provided by this analysis Specific Phase Search Including specific packages for Gold and Silver minerals This type of analysis is suitable to find PGM lowgrade levels of ore minerals and other lowgrade minerals like gold and sil ver T race a n d p a t h f i n d e r p h a s e s c a n a l s o b e c h a r a c t e r i z e d O n c e t r a c e p h a s e s h a v e b e e n i d e n t i f i e d d a t a s u c h a s g r a i n s i z e d i s t r i b u t i o n c l a s s i f i e d images and particle counts can be provided Actlabs has extensive experience in mineralogical analyses of precious metals as we ll as the ore minerals Using our FEG Field Emission Guns equipped QEMSCANMLA we are able to find and characterise fine micronsiz ed or sub micron sized 03 m Gold or Silver particles locked in the pyrites quartz and other gangue minerals W e can perform total precious metal deportment useing FEG SEBSE Imaging Spectrum Field Emission Gun technology enables us to take highquality Backscattered Electron for textural and Secondary Electron for topo graphic images In addition both our MLA and QEMSCAN are equipped with two BRUKER SSD EDS detectors The combination of detectors with the high intensity bright FEG source provides rapid and therefore low cost analysis for the customer Electron Probe Microanalyzer Whenever the major and minor elements of a mineral shall be identified and quantified with a high precision EPMA insitu analy ses will be the solution Actlabs has a procedure for oxides silicates sulphides and sulphates as well as alloys EPMA analysis can be done in conjunction with MLA and QEMSCAN measurements as a complementary method Petrographic Analysis For detailed description the rock its mineralogy and textural relationships as well as identification of the Coal component s Actlabs employs transmittedreflected petrographic microscopy Olympus BX52 on polished thin sections and polished sections For more details and quotation inquiries please contact geometallurgyactlabscom
