A novel compound 4-amino-5-mercapto-1,2,4-triazole was first synthesized, and its selective adsorption mechanism on the surface of chalcopyrite comprehensively investigated using UV–vis spectra, zeta-potential, Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron measurements (XPS), time-of-flight secondary ion mass spectrometry (ToF-SIMS), principles calculations. The experimental computational results consistently demonstrated that AMT would chemisorb onto by formation a...
The acid neutralization process is widely recognized for its effectiveness in the dealkalization of red mud, and it faces challenges solid–liquid separation due to formation numerous colloidal components. This study investigated impact calcium-containing compounds (CaO, CaCl2, CaCO3, CaSO4) on efficiency mud during process. sodium leaching reached 95.6% when was reacted with 8% sulfuric 10 min a stirring speed liquid solid ratio 700 r/min 5:1, respectively. replacement using simulated waste...
Abstract The synergistic control of the crystal morphology and size α‐hemihydrate gypsum (α‐HH) was achieved by adjusting Na 2 SO 4 concentration maleic acid content. Maleic primarily regulated α‐HH through surface adsorption. determined tailoring maximum relative supersaturation ( S max ) during crystallization. Higher concentrations led to higher smaller sizes. in a 9% solution 4.5 times that 6% solution, resulting significant decrease from approximately 40–18 µm as increased 9%, while...
A facile method to transform flue gas desulfurization gypsum (FGD gypsum) α- calcium sulfate hemihydrate (α-HH) whiskers with high aspect ratios mediated by cetyltrimethylammonium bromide (CTAB) and KCl in glycerol-water solutions was studied. Addition of facilitated the dissolution dihydrate (DH) created a much higher supersaturation, which could come into being larger driving force for phase transformation from DH α-HH. CTAB as crystal modifier can significantly promoted 1-D growth α-HH...
The conversion of CaSO4·2H2O (DH) to CaSO4·1/2H2O (HH) was facilitated by increasing glycerol content from 55% 85% in glycerol–water mixtures; the average length and diameter produced α-HH crystals decreased 60.97 7.21 μm 15.21 5.17 μm, respectively, resulting a decrease aspect ratio 4.06 1.41. phase transformation reduced dramatically 30 3 h. As increased mixtures, an increase maximal relative supersaturation ion diffusion rate were hypothesized as explanations for morphology change...
A brand new method to prepare α-CaSO<sub>4</sub>·0.5H<sub>2</sub>O with low aspect ratios from flue gas desulfurization gypsum in glycerol-water solution was presented, which NaCl used as the phase transition accelerator and C<sub>4</sub>H<sub>4</sub>O<sub>4</sub>Na<sub>2</sub>·6H<sub>2</sub>O crystal modifier.
Abstract Here we reported a method to simultaneously control the particle size and morphology of α‐Ca SO 4 ·1/2H 2 O (α‐ HH ) prepared from flue gas desulfurization gypsum by adjusting succinic acid concentration glycerol content under mild conditions. Succinic controlled crystal adsorption onto α‐ surfaces, size, in which an increase maximal relative supersaturation ( S max nucleation rate was hypothesized cause change size. Then, based on method, with different sizes but almost same...
The characterization and leaching mechanism of REEs from phosphogypsum (PG) in HCl was studied in-depth. contained the PG were 208 ppm, which Y, La, Ce, Nd four most abundant elements. modes occurrence rare earth elements (REEs) quantified using sequential chemical extraction (SCE) method. Among five REE species, metal oxide form accounted for largest proportion, followed by residual, organic matter, ion-exchangeable fractions, bound to carbonates least. From comparison distributions calcium...
