Summary: A binary collector system containing sodium oleate/salicylhydroxamic acid (NaOL/SHA) was optimized to improve the floatability of cassiterite at low concentrations. The microflotation experiments demonstrated that the NaOL:SHA (1:2) mixture performed better than the single collector, with a flotation recovery of cassiterite above 90% at a pH of 8.0 and a total collector concentration of 5 x 10-5 mol/L. The synergism between NaOL and SHA was explained through various measurements and calculations, indicating strong O-Sn chemical bonds formed on the cassiterite surface.

Summary: In this study, the effects of water salinity on the flotation performance of lead and zinc sulfide minerals were investigated. The results showed that higher concentrations of NaCl salt solutions led to higher recoveries of PbS and ZnS. Additional ions in seawater, such as Ca2+ and Mg2+, significantly reduced the recovery of PbS and ZnS. A surface complexation model for ZnS was developed and validated, which accurately predicted the behavior of ZnS particles under various pH and NaCl concentrations. Theoretical analyses revealed the repulsive and attractive interactions between particles and bubbles, as well as the influence of NaCl concentration.

Summary: In recent decades, microbubble flotation has been extensively researched for fine mineral separation and beneficiation. It offers advantages over conventional flotation, such as high grade and recovery and low reagent consumption. This review summarizes the latest advances in microbubble flotation for fine mineral particles. Microbubbles possess small bubble size, large specific surface area, high surface energy, and selectivity, allowing them to easily attach to hydrophobic particles or large bubbles, reducing the probability of particle detachment. Various methods, such as pressurized aeration, electrolysis, ultrasonic cavitation, and photocatalysis, can be used to generate microbubbles. Fine-particle flotation equipment includes microbubble release flotation machines, centrifugal flotation columns, packed flotation columns, and magnetic flotation machines. Microbubble flotation has shown superiority in the beneficiation of ultrafine coals, metallic minerals, and nonmetallic minerals. Mechanisms supporting the promotion of fine-particle flotation by nanobubbles include particle agglomeration, nanobubble stability in aqueous solutions, and enhancement of particle hydrophobicity and flotation dynamics.

Summary: This research systematically investigated the influence of calcium ions on the adsorption behavior of sodium oleate and its response to quartz flotation. The addition order of calcium ions was found to affect the flotation recovery of quartz. The formation of Ca-OOCR colloid precipitates reinforced the adsorption of NaOL and Ca2+ onto the quartz surface. The adsorption mechanism of Ca-OOCR colloid precipitates played a more important role in the adsorption of sodium oleate and calcium ion species, as well as its response to quartz flotation.

Summary: The study investigates the particle characteristics and metal distribution during the fine crushing of waste PCBs using a shear crusher. The results show that better crushing efficiency is achieved with a feeding concentration of 183 g/L and crushing time of 60s. The coarse and fine particles of waste PCBs have higher circularity and smaller aspect ratio compared to medium-size particles. The main metal elements are distributed in waste PCBs with different particle sizes, and the total metal content in the coarse crushed products is higher than that in the fine crushed products.

Summary: This study focused on the basic research of flotation separation of dolomite from brucite using guar gum (GG) as a selective regulator. The flotation tests showed that the use of GG inhibited the floating of dolomite but did not affect the floatability of brucite. Contact-angle measurements and zeta-potential measurements confirmed the difference in floatability between dolomite and brucite after the action of GG. Infrared-spectrum analysis and X-ray photoelectron spectroscopy detection provided further evidence of the interaction between GG and the mineral surfaces.

Summary: Pentaethoxylated tallow amine (PTA) was introduced as a selective collector for separating siderite from hornblende for the first time. The results showed that PTA strongly collected hornblende but not siderite, leading to enhanced differences in flotation performance. The adsorption measurements revealed that hornblende adsorbed more PTA than siderite, increasing the hydrophobicity of hornblende. The analysis of zeta potential and FTIR confirmed that the strong adsorption of PTA on hornblende was due to hydrogen bonding and electrostatic attraction. The use of PTA as a collector achieved effective separation of hornblende from siderite.

Summary: This study used dodecylamine (DDA) as a collector and investigated the role and adsorption mechanism of a new regulator sodium monododecyl phosphate (SMP) in the flotation separation of brucite and calcite. The results showed that SMP significantly increased the flotation recovery of calcite and achieved a large difference in flotation recovery between brucite and calcite. SMP selectively increased the adsorption capacity of calcite for DDA, and its presence affected the contact angle of calcite and brucite. Further analysis revealed the impact of SMP adsorption on the surfaces of brucite and calcite.

Summary: More efficient liberation of valuable minerals from gangue is highly beneficial to the comminution process and downstream beneficiation processes. However, the impact of particle-bed breakage on liberation compared to traditional grinding remains controversial. This study compared the liberation performance of iron oxide minerals using two different breakage methods (particle-bed breakage and ball mill grinding). The results showed that particle-bed breakage only slightly improved the liberation of iron oxide minerals, with a maximum difference of 5% in the proportion of liberated minerals. Overall, the difference in liberation distribution between the two breakage methods was not statistically significant in most size/composition classes.

Summary: In this study, we used diammonium hydrogen phosphate (DHP) to regulate the flotation separation of brucite and calcite. DHP was found to have activation and inhibition effects on calcite and brucite flotation, respectively, resulting in a significant recovery difference between the two minerals. Further analysis showed that DHP affects the contact angle and zeta potential of calcite and brucite surfaces, leading to differences in their floatability. In addition, infrared and X-ray photoelectron spectroscopy tests revealed the adsorption behavior of DHP on the mineral surfaces, confirming its stronger affinity for calcite than brucite.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
