“…However, in most cases, the recovery of some minerals exhibits large differences in the single mineral flotation tests and actual ore flotation methods under the same flotation conditions, which reveals that the interactions of minerals affect the flotation behavior of the minerals. This interaction effect may be due to a combination of factors, including pH variation, dissolved ions [3], aggregation/dispersion [4,5], competitive adsorption [6], or particle sizes [7,8]. Among these reasons, the influence of fine particles plays an important role in many flotation processes [9][10][11].…”

Extended-DLVO (Derjaguin-Landau-Verwey-Overbeek) theory is applied to calculating the interaction energy between particles in flotation process in the paper. This study investigates and compares the floatability of magnesite, dolomite, serpentine, and quartz in single mineral flotation and artificial mixture flotation with DDA as collector. The results showed that when the pH, dissolved ions, and competitive adsorption had a minor influence on their floatability, fine magnesite and dolomite largely decreased the recovery of quartz. SEM analysis on the flotation products demonstrated severe masking of fine particles on the surface of quartz. The Extended-DLVO theory was applied to calculate the interaction energy between the minerals, and the results showed that the interaction forces between magnesite and quartz, serpentine and quartz, and dolomite and quartz were attractive; therefore, fine magnesite, serpentine, and dolomite particles are easily masked on the surface of quartz. The calculation results agree with the experiment results and explain the mechanism of particles interaction and the reasons for the inconsistency in single mineral flotation and actual ore flotation. The particles interaction behavior is important in flotation process, and the interaction energy calculation is helpful for evaluating this behavior.

“…The particle–particle interaction force and energy calculation can be obtained via applying the Derjaguin approximation numerically 42 on the plate–plate interaction energy calculation. The PBE was further determined as the difference between the numbers of the newly generated particles and particles consumed in the aggregation toward larger particles: 37,38,43 where β ij is an aggregation kernel which is related to the energy profile of the particle–particle interaction calculated above (more details included in ESI†).…”
