I have been evaluating collector performance under different pH conditions using pure minerals (Zinc Ferrite, Zinc Oxide, Hematite, and Magnetite) with a particle size of
Floatability in collectors is related to wettability and therefore to maximum adsorption on the mineral. The other concentration of the collector can interfere with the process. Therefore, for each collector you need to estimate the maximum adsorption. It depends on the nature of the mineral, the particle size, the pH of the collector...
