“…The objective functions considered in this study were the minimum conductivity (J 1 ), the minimum turbidity (J 2 ), the minimum viscosity (J 3 ), and the minimum interfacial tension (J 4 ). These objectives were combined into a scalar goal as follows: J = w 1 J 1 + w 2 J 2 + w 3 J 3 + w 4 J 4 (10) where w 1 , w 2 , w 3 , and w 4 are weighting factors, which can be calculated using the rank sum method [16,[43][44][45].…”

“…In the mining industry, these combinations are used to improve flotation and mineral separation processes. Surfactants are used as collectors to float valuable minerals, while polymers modify the viscosity and stability of emulsions, and oils act as lubricants to reduce friction and facilitate separation processes [9,10]. These combinations are also used in other industries, such as the production of cosmetics, food, paints, detergents, and pesticides.…”

This research aimed to study the effects of individual components on the physicochemical properties of systems composed of surfactants, polymers, oils, and electrolytes in order to maximize the recovery efficiency of kerosene while minimizing the impact on the environment and human health. Four independent factors, namely anionic surfactant sodium dodecylbenzene sulfonate (X1) (SDBS), oil (X2) (kerosene), water-soluble polymer poly(ethylene glycol) (X3) (PEG), and sodium chloride (X4) (NaCl), were studied using the full factorial design (FFD) model. Four output variables, namely conductivity (Y1), turbidity (Y2), viscosity (Y3), and interfacial tension (IFT) (Y4), were taken as the response variables. All four FFD models have high coefficients of determination and low errors. The developed models were used in a multi-objective optimization (MOO) framework to determine the optimal conditions. The obtained optimal conditions are X1 = 0.01, X2 = 50, X3 = 5, and X4 = 0.1, with an error of 0.9414 between the predicted and experimental objective function values. This result shows the efficiency of the model developed and the system used for the recovery of kerosene, while also having a positive effect on the protection of the environment.

“…According to earlier research, the addition of lead ions can enhance mineral flotation by increasing the collection of sulfided minerals by xanthate, promoting the sulfide flotation of oxide minerals such as azurite and malachite, and flotation in general [ 13 , 14 ]. In their study of lead ions-activated smithsonite, Zhang et al [ 15 ] reported that Pb 2+ undergoes an ion exchange reaction with the surface of smithsonite to form PbCO 3 that can be stably adsorbed on the surface of the mineral, which has a key involvement in the sulfide flotation of smithsonite to the reinforcement.…”

Cerussite is a lead oxide mineral resource that is typically enriched through sulfidization flotation. The surface sulfidation degree and the high solubility of cerussite strongly affect the flotation ability of cerussite. In the current work, lead ions were used to pretreat cerussite to intensify its sulfidization flotation. The sulfidization mechanism regulating the lead ions pretreatment on cerussite was investigated by the micro-flotation test, ToF-SIMS, zeta potential measurement, adsorption test, and XPS. The results from the micro-flotation test demonstrated that the floatability of cerussite could be improved by adding an appropriate amount of lead ions. Compared with the treatment involving only Na2S, the maximum recovery increased by 17.57%. Adsorption experiments showed that lead modification improved the stability of xanthate products on the surface of cerussite. According to the measurement of zeta potential and the results of ToF-SIMS, the addition of lead ion Pb pretreatment increased the number of active Pb sites adsorbed by xanthate, thereby improving the formation of hydrophobic Pb-dilute precipitate. Therefore, the interaction between lead ions and the surface of cerussite enhances the strength and stability of the hydrophobic layer, resulting in enhanced hydrophobicity of cerussite.

“…Flotation is the most widely used and effective beneficiation method for separating fine refractory minerals (Ni et al, 2016). However, flotation is a complex physical and chemical process influenced by many factors, including the properties of the ore itself, flotation equipment parameters, and reagents (Xu et al, 2012;Polat et al, 2003;Feng et al, 2022;Jovica et al, 2018;Zhang et al, 2019). The flotation kinetics is an essential aspect of the study of the flotation process.…”

Flotation kinetic models can be applied to describe the flotation process and to predict mineral recoveries. However, the size composition of the target minerals in the feed ore fluctuates considerably, resulting in insufficient accuracy with flotation kinetic models. There have been many studies that focus on the investigation of flotation kinetics with different particle sizes, while the optimization methods for flotation kinetic models based on particle size effects have not been reported. In this paper, flotation tests, optical microscope observations, and particle size analysis were used to identify the reasons for the decrease in accuracy of the flotation kinetic model due to changes in the composition of molybdenite particle size. Additionally, an optimization method for the flotation kinetic model was developed based on the particle size effect. The test results show that the accuracy of the flotation kinetic model for fixed particle size minerals is very high, but the predicted results for flotation recoveries of different particle size mineral mixtures have large deviations. The poor accuracy might be due to the autogenous carrier effect caused by the particle size composition fluctuating considerably. The optimization method for the flotation kinetic model is based on the particle size effect. The model can accurately describe the flotation process of molybdenite with different size compositions of molybdenite and predict the flotation recovery of molybdenite.
