Summary: The impact of particle shape and surface properties on mineral systems has been overlooked in previous literature. This study investigated the effects of morphological variations on flotation kinetics using coal particles. The results showed that increased milling time resulted in increased roundness and roughness of the particles, leading to higher flotation rates. The findings were further supported by theoretical calculations of energy barriers.

Summary: In this study, experiments were conducted to investigate the classification performance of coal slime. It was found that the misplacement of fine particles in the underflow was mainly caused by the presence of fine gangue components. Increasing the feed concentration appropriately can reduce the adverse effect of particle density on classification. This work provides insights into the migration mechanism of multi-component particles during the classification of coal slime.

Summary: The flotation process of fine non-coking coal from kaolinite was improved by the addition of anionic polyacrylamide, which interacted with kaolinite and coal particles through hydrogen bonding. Anionic polyacrylamide selectively flocculated kaolinite particles, reducing kaolinite pollution in the froth and decreasing the amount of kaolinite particles coating the clean coal surface. Ultimately, the flotation selectivity was enhanced by anionic polyacrylamide pre-conditioning.

Summary: In this study, a two-stage direct flotation method with the BS collector and dodecane reagent system was used to conduct a three-product slime flotation experiment, aiming to maximize flotation efficiency, reduce flotation tailings, and increase ash content. Modern analytical methods, such as X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR), were employed to analyze the surface characteristics of the samples and their interaction with collectors. The results showed that the secondary flotation tail coal had significantly higher ash content compared to the primary one with increasing reagent dose. The surface hydration membrane and BS collector formed a hydrogen bond through the -OH functional group, leading to increased hydrophobicity and flotation effectiveness.

Summary: Fluidization is effective in improving the separation of coarse particles. In this study, three-dimensional computational fluid dynamics (CFD) modeling is used to investigate the complex behavior of irregular coarse particle fluidization in a fluidized bed flotation cell. A modified drag model considering the particle shape factor is employed to account for the irregularity of the particles. Comparison between simulated and experimental data shows that the irregular particle drag model has a relative error of 3.9%, which is significantly better than the spherical particle drag model. The CFD model further reveals the effects of particle density and fluidization liquid velocity on bed expansion height. The fluidization behaviors of the particles in different zones of the fluidized bed flotation cell are analyzed, providing valuable insights for the flotation of coarse particles in fluidized beds.

Summary: This paper analyzes the obstacles inhibiting the flotation of fine particles and proposes solutions for the wetting zone between bubbles and particles during collision. It is found that the efficiency, rather than frequency, of collisions is the main problem in fine particle flotation. Additionally, there is a thermodynamic lower size limit for flotation of hydrophobized particles, which is weakly dependent on bubble size. Electrostatic attraction, increased hydrophobicity, and the presence of fine bubbles are crucial for achieving fast flotation and high recovery of fine particles. Different collectors, such as hexylamine and hexamethyldisilazane, are shown to enhance the hydrophobicity and recovery of silica particles, with varying selectivity. A new collector, disodium dodecyl phosphate, significantly increases the hydrophobicity and recovery of magnesite particles, both alone and in mixture with silica particles.

Summary: With the assistance of mechanical ball milling, the partially oxidized micro-sponge iron (micro-Fe0@Fe2O3) achieves significantly improved removal of Cr(VI) across a broad pH range. Mechanical force eliminates the surface oxide layer and exposes the Fe0 core, leading to sustained reduction of Cr(VI). The efficiency of micro-Fe0@Fe2O3 is strongly influenced by dissolved oxygen, with higher DO resulting in the generation of stable reductant Fe(II) under acidic conditions, while DO consumption hinders the reduction of Cr(VI) under alkaline conditions due to increased pH. Parameters of ball milling operation, especially rotation speed, have a significant impact on the removal of Cr(VI).

Summary: High molecular weight partially hydrolysed polyacrylamide (PHPA) is commonly used in mineral exploration drilling to increase fluid viscosity and help maintain the suspension of fine particles. However, clarifying these suspensions can be difficult, and previous studies have found that anionic flocculants are ineffective. This study confirmed that nonionic flocculants can successfully aggregate the particles, indicating that the charged tails of adsorbed PHPA prevent anionic flocculants from accessing the particle surfaces.

Summary: Mineral processing requires large amounts of water, and reducing water consumption through recirculation and closing water loops is important. However, this can lead to the accumulation of contaminants in the process water, which can negatively affect the process performance. In this study, the impact of microorganisms on flotation performance was investigated, and ion exchange was evaluated for removing dissolved sulfur species and microorganisms from water. The results showed that adding microorganisms had a positive effect on flotation selectivity, especially for nickel. Different water types, process water and final tailings water, behaved slightly differently. Ion exchange proved to be effective in removing sulfur species and microorganisms, and dissolved air flotation was a successful pretreatment for ion exchange in removing microorganisms.

Summary: This study demonstrates that the use of a DDA/DDTC mixed collector system can significantly improve the flotation performance of smithsonite. The synergistic effect between DDA and DDTC is confirmed, and the mixed collector system contributes to a decrease in solution surface tension. The use of FT-IR and XPS confirms the simultaneous physisorption and chemisorption of DDA and DDTC on the smithsonite surface, and contact angle measurements show that the mixed collector effectively enhances the hydrophobicity of smithsonite. Molecular dynamics simulations reveal the multilayer adsorption of DDTC and DDA on the smithsonite surface, with DDTC promoting the adsorption of DDA.
