Critical Evaluation
Value of the Information & Strength of the Argument
The presentation provides valuable insights into the limitations of current industrial flotation chemistry practices and presents a compelling argument for a systems-based approach. Forbes effectively uses case studies from her group’s research to illustrate how understanding fundamental chemistry can lead to practical improvements. The argumentation is solid, grounded in experimental evidence and collaborations with industry partners. However, the talk is a high-level overview, and some claims would benefit from more detailed data or references to specific publications.

Contribution & Novelties
The presentation offers a novel perspective by framing flotation chemistry as an integrated system, moving beyond traditional reagent trial-and-error. It showcases innovative applications of advanced analytical techniques (ToF-SIMS, NMR, induced polarization) to industrial problems, such as predicting pyrite reactivity and measuring residual reagents in process water. The development of aerosol collector addition and the finding that critical coalescence concentration is hydrodynamics-dependent are significant contributions. The talk also emphasizes the importance of knowledge transfer to bridge the gap between academic research and industrial practice.
