Our Team

Stefan Nadolski

CEO, P.Eng., PhD (Mining) , MASc. (Mining), B. Eng. (Mech)

Stefan Nadolski is a founder of Minpraxis Solutions. He has worked for over 13 years in the mining industry on numerous sensor-based sorting, comminution, mechanical design and energy efficiency projects.

Stefan has a PhD and a master’s degree from the University of British Columbia in the field of mining engineering. Working closely with a block cave mine, his PhD research focused on developing integrated mine and mill approaches for block caving operations. He has contributed to over 25 publications in the fields of mining and mineral processing, two of which were awarded the CEEC medal for their significance to the field of energy efficient comminution.

Outside of being a consultant, Stefan enjoys studying languages and stand-up paddling on the Burrard Inlet of Vancouver.

Gonzalo Pizarro

COO, MASc. (Mining Eng.), B. Eng. (Mining Eng.)

Gonzalo has over five years of experience in project design, analysis, and simulation. He also has experience working with Virtual reality and Augmented Reality for the mining industry, creating customized experiences to improve training and data visualization. His expertise lies in geotechnical, mine design, and mineral processing. He has been involved in various industrial projects related to rock characterization, mineral processing, and 3D visualization of an actual mineral processing plant (Spence operation, BHP) that was used to train new personnel and to analyze and improve the design.

Gonzalo is also a Ph.D. student at the University of British Columbia working in the field of geotechnical and metallurgic characterization combined with mine-to-mill and also using his skills in 3D visualization.

Connor Belvis

EIT, B. Eng. (Mech)

Connor is a Mechanical Engineer-in-Training. His work consists of engineering design, 3D modelling, and FEA simulation. With 2 years of project design and prototyping experience, Connor is using his skills in creative and collaborative problem solving to contribute to the projects at Minpraxis Solutions Ltd.
Connor graduated from the University of British Columbia-Okanagan with a BASc degree in Mechanical Engineering. His academic training was focused in materials selection, manufacturing processes, and CAD/CAM design.
