“…Sample A underwent the joint action of untreated copper ions and sodium oleate. As can be seen from Figure 9, the absorption peak of wave number 3629 cm −1 corresponds to the vibration absorption peak of hydroxyl, and the other two peaks at 2935 cm −1 and 2860 cm −1 can be attributed to the vibration absorption peak of the C-H bond in the methyl group and methylene in sodium oleate, respectively [20,21].Sample B, sample C and sample D had the joint action of treated copper ions and sodium oleate. Compared with sample A, the intensity of vibration absorption peak of the C-H bond corresponding to methylene and methyl groups of sodium oleate in sample B and C is significantly enhanced, indicating that the increased adsorption of sodium oleate on the sample surface.…”

In this study, electrochemistry pretreatment flotation of muscovite was carried out and the flotation behavior and mechanism of muscovite in the system of sodium oleate and Cu2+ion was characterized by solution pH value detection, solution conductivity detection, zeta potential, infrared spectrum and the electronic energy spectrum. The results indicated that under the conditions of muscovite mass of 10.00 g, pulp mass concentration of 13.33%, flotation speed of 1750 r/min, sodium oleate concentration of 9.20 × 10−4 mol/L and Cu2+ concentration of 6 × 10−5 mol/L, electrochemical pretreatment of Cu2+ could strengthen the activation of muscovite. Electrochemical pretreatment of Cu2+ solution can inhibit the hydrolysis of copper ions, increase the content of Cu2+ in the solution, strengthen the adsorption of Cu2+ on the muscovite surface, and enhance the electrostatic adsorption of sodium oleate on the muscovite surface, thereby strengthening the physical and chemical adsorption of sodium oleate on the muscovite surface.

“…In the addition of the oleic acid as collector, several new peaks are observed in the spectra of (a) scheelite, (b) calcite, and (c) fluorite. The new peaks at 2852 cm −1 and 2922 cm −1 are due to the -CH3 and -CH2 stretching bands in the oleic acid, indicating the chemical adsorption of oleic acid on each Ca-mineral surface [3,17]. This chemical adsorption consists of monolayer adsorption, allowing only one reagent to react to each available site on the mineral surface for adsorption.…”

“…There are various types of tungsten minerals. Among them, scheelite (CaWO 4 ) is considered as an economically important mineral [2,[4][5][6][7]9,[11][12][13][14][15][16][17]. To be specific, scheelite is easily ground to fine particles during crushing and grinding processes due to its brittleness [1,18,19].…”

Tungsten is an essential metal for the manufacture of special alloys, which is in constant demand due to the development of the industry. The recovery of scheelite from undeveloped tungsten ore in South Korea was investigated to improve the flotation performance for high grade and recovery of concentrate. To investigate the interaction between the flotation reagents and the minerals, the adsorption experiments of oleic acid as a collector on Ca-bearing minerals, such as scheelite, calcite, and fluorite were carried out. This reaction was confirmed chemical adsorption by analysis of zeta potential and FTIR analysis. The batch test was performed using a raw ore to enhance the grade and recovery of the scheelite concentrate. It was obtained at the optimal conditions for high WO3 grade and recovery of scheelite concentrate by using a simple process. In particular, the sodium carbonate used as a pH modifier was investigated to increase scheelite flotation performance by supporting the selective depression of Ca-bearing gangue minerals. Furthermore, a locked cycle test (LCT) was carried out based on batch test results for the design of a continuous pilot plant.
