This dataset includes experimental data used for analysis. It contains raw and processed data from the following measurements: Microflotation tests (scheelite, calcite, apatite, fluorite) RData of the MLA measurements SOPAT bubble size measurements Bubble pressure tensiometry Data Dynamic Foam Analyzer (DFA) results Atomic Force Microscopy (AFM) surface roughness parameters with and without CS Microflotation data.xlsx contains scheelite, calcite, apatite and fluorite recoveries of the microflotation tests under various CS type, and dosage conditions. PFM_RData of the MLA measurements that have been used for the Particle-based kinetic flotation model SOPAT-bubble-detection and dataSOPAT.csv include SOPAT images and results for each investigated CS type. Dynamic Surface Tension Measurements.xlsx shows dynamic surface tension as a function of interface age for each investigated CS type. DFA_Investigation.csv includes results of froth height, drainage half-time, froth life half-time and liquid content for each investigated CS type. AFM_Raw data.xlsx includes AFM roughness data Sa, Sq, Sz, Ssk and Sku for each mineral before and upon CS treatment.
