Synthesis and characterization of a novel collector for the desulfurization of fine high-sulfur bauxite via reverse flotation

Flotation separation influenced by the rheological properties of diaspore-pyrite mixed pulp

“…As shown in Table 2, the surface potential of pyrite decreased with increasing SHMP concentration at pH 8-9. Electrostatic attraction was also considered one of the mechanisms for the interaction between the collector and pyrite (Cheng et al, 2023). The electrostatic energy curve for the particles in the pulp gradually moved to the right with increasing SHMP concentration as shown Fig.…”

“…The methods used for desulfurization of high-sulfur bauxite were wet desulfurization, calcination desulfurization, flotation desulfurization, microbial desulfurization and so on (Wu et al, 2020;Zhao et al, 2021) , and flotation has been widely applied because of its low cost and simple operation. Flotation is a method to separate target minerals from gangue minerals by different effects of minerals on liquid and gas in pulp according to the differences in physical and chemical properties of mineral particles (Cho et al, 2022;Jin et al, 2023;Sajjad and Otsuki, 2022;Saneie et al, 2022), which is one of the most effective mineral processing methods for separating and enriching target minerals (Cook and Gibson 2023;Shao et al, 2023;Xiao et al, 2022), especially for high-sulfur bauxite (Cheng et al, 2023). The main sulfide mineral in bauxite is pyrite with strong hydrophobicity, for which the most effective separation method is reverse flotation.…”

“…The main sulfide mineral in bauxite is pyrite with strong hydrophobicity, for which the most effective separation method is reverse flotation. The agent and flotation conditions are very important to obtain well mineral processing effect in the process of high-sulfur bauxite flotation (Chen and Zhang, 2022;Cheng et al, 2023). Zhou et al, (Zhou et al, 2022) synthesized quaternary ammonium ionic liquids using tetradecyl dimethyl benzyl ammonium chloride and sodium isobutyl xanthate as raw materials, which was used as flotation collector in reverse flotation of silicate and sulfur in diasporic high sulfur and high silicon bauxite.…”

Copper Oxide Anchored Carbon Nanofibers: A Versatile Platform for Multiplex Detection of Antibiotics, Heavy Metals and Pesticides

“…[22,31,35] NPs are pervasive because of their small particle size, high surface free energy, large specific surface area, high reactivity, strong chemical activity, and large adsorption capacity. [36,37] A, recent study reported the development of an electrochemical sensor using biosynthesized CuO nanoparticles for the detection of 4 nitrophenols. CuO nanoparticles acted as a catalyst and showed reproducibility and selectiviliyt towards the analystes and was also able to perform real sample analysis.…”
