"FLOW CUTTER IN MINERAL CONCENTRATE FALLOUT: VALIDATION OF FLOW VELOCITIES AND CUTTER".
"• Felix Toconas Mejía.
• Geologist.
• Responsible for quality control South America of Glencore. Felix was born, raised, and educated through secondary school and university in Bolivia, earning a degree in Geology from the Technical University of Oruro. He later pursued a master's degree in "quality strategies" at the Andean University "Simón Bolívar".
He attended various training courses in different areas of geology, primarily in mineral sampling; as a result of these trainings and experience, he generated an article for the 10th World Conference on Sampling and Blending.
For over 10 years, he worked for different companies in the exploration of precious minerals and base metals in environments of the Precambrian shield, Paleozoic and Cenozoic; using tools such as satellite imagery, geochemistry (stream sediments, soils and rocks), geophysics (airborne and ground) and drilling (RC and Diamond).
For the past 21 years, he has been working at Glencore as the person responsible for quality control for South America in mining operations, smelters, and concentrate shipment ports.
Among his achievements: in metallurgical plants, controlling the differences in laws between mine and concentrating plant, with the implementation of sampling systems, weighing and chemical assay entering into metallurgical balances. In chemical laboratories, implementation of measurement criteria for precision and bias in mineral sample assays. Finally, at shipping ports, minimizing the differences in tonnage, laws, and moisture between mine and final destination of the concentrates."
