Services by Segment
Tailored solutions for researchers, companies, and public organizations
Concentrate and Tailings Characterization
Problem
You need to assess metallurgical recovery, identify losses in tails, or characterize legacy tailings with revalorization potential.
Technology
Combination of ICP-MS for trace elemental analysis, XRD for phase identification and QEMSCAN for mineral distribution.
Result
Detailed metallurgical balance, loss identification, and process optimization proposals for concentration circuits.
Mineral Liberation Studies
Problem
Grind size directly affects recovery: you need quantitative data to define the optimal degree without over-grinding.
Technology
Automated particle analysis with TESCAN TIMA-X, quantifying liberation per mineral phase and size class.
Result
Liberation curves per mineral and per particle size, with recommendations for adjusting the comminution circuit.
Automated Quantitative Mineralogy
Problem
You need precise knowledge of the mineralogical composition, liberation degree and phase distribution of your ore samples to optimize metallurgical processes.
Technology
Automated FE-SEM/EDS with high-throughput EDS detectors. Quantitative modal analysis with micrometric resolution.
Result
Complete mineralogical report: modal composition, liberation degree, mineral associations and phase distribution maps.
Capabilities and Equipment
Cutting-edge technology for advanced materials characterization
