Specialized gas dispersion expertise
Flotation Metrics exists to help the flotation industry use gas dispersion more deliberately
Gas dispersion is an important driver of flotation performance, but in many operations it is still not routinely measured, compared, or used to guide operating decisions.
We believe every flotation cell should be understood through gas dispersion – not as an academic concept, but as a practical way to improve frother strategy, air rate, froth depth, cell balance, and circuit performance.
1. We believe gas dispersion should be measured
Every flotation circuit depends on gas dispersion, but too few operations have the tools or support to use it deliberately.
2. We understand the fundamentals
We work at the intersection of flotation research, plant operations, reagent response, and measurement tools – staying close to the state of the art while focusing on practical application.
3. We make it usable
We turn gas dispersion measurements into clear recommendations for frother strategy, air rate, froth depth, cell balance, and circuit performance.
Led by a flotation gas dispersion specialist
Mark Lepage, Ph.D.
Founder & Technical Lead, Flotation Metrics
Mark has spent much of his research career focused on making gas dispersion more practical for flotation operations.
Through McGill University and industrial research work, he has planned and performed gas dispersion studies involving bubble size, gas holdup, froth behaviour, frother response, and custom measurement tools.
Through Flotation Metrics, Mark applies that experience to help clients use gas dispersion to better understand and improve flotation performance.
Ph.D. in Mining and Materials Engineering from McGill University
Extensive experience performing gas dispersion studies
Specialized knowledge of flotation hydrodynamics and process interpretation
Current research focus on applying gas dispersion to industrial flotation operations
