Abstract ：
为了解决低品位铝土矿石正浮选脱硅过程中传统捕收剂油酸钠使用效果欠理想问题,研究以铝土矿中常见代表性铝硅矿物一水硬铝石和高岭石为分离对象,开展了油酸钠与油酸钠+椰油酰甘氨酸钠捕收一水硬铝石和高岭石纯矿物试验,以及浮选分离一水硬铝石与高岭石人工混合矿试验,量化了单一捕收剂与混合捕收剂的浮选性能差异,最后通过接触角测试、Zeta电位测试、红外光谱分析和X射线光电子能谱(XPS)分析等手段揭示了捕收剂与矿物表面的作用机理.浮选试验表明:在矿浆pH=10,油酸钠+椰油酰甘氨酸钠混合摩尔比为 1∶1、用量为 3×10-4 mol/L条件下,一水硬铝石与高岭石纯矿物浮选回收率差异达 83.86 个百分点,人工混合矿(一水硬铝石与高岭石的质量比为2∶1)浮选精矿铝硅比由7.16 提高到8.93,Al2O3 回收率由77.27%提高到82.94%,达到了较好的分选效果.机理分析表明:油酸钠+椰油酰甘氨酸钠在一水硬铝石表面的吸附作用比油酸钠更强,椰油酰甘氨酸钠可以促进油酸钠在一水硬铝石表面的吸附,阻碍油酸钠在高岭石表面的吸附,从而可以改善一水硬铝石与高岭石的浮选分离效果.

Abstract ：
Magnesite in nature mainly exists in two structures, crystalline and cryptocrystalline. The difference in crystal structure causes minerals to exhibit different surface properties, such as solubility and hydrophobicity, during the flotation process. In the flotation process, the commonly used anion and cation regulators will promote different interactions between the two crystalline structures magnesite and the collector, but the specific influence mechanism on the two crystal structures is not clear. In this paper, the effects of anions and cations, such as Fe3+, Ca2+ , SiO23- and CO23-, on the floatability of two crystalline magnesites were studied under the action of dodecamine cation collector and sodium oleate anion collector. The results show that Fe3+ has obvious inhibitory effect on minerals in dodecamine system, the recovery rates of crystalline magnesite and cryptocrystalline magnesite decrease by 70% and 10%, respectively. Ca2+, SiO23- and CO23- have certainly activating effects, among which CO23- has the strongest effect, and the recovery rates of two crystalline magnesites increases by 70% and 40%, respectively. In the sodium oleate system, Fe3+ and Ca2+ have inhibitory effects on the flotation of minerals, the recovery rates of the two minerals decreases by 55% and 20%, respectively, when Fe3+ is reacted. Ca2+ and Mg2+ have the activating effect on the surface of minerals, and the recovery rates of crystalline and cryptocrystalline magnesite increase by 10% and 25%, respectively. The different crystalline structures of magnesite affect its flotation characteristics under ionic conditions. The addition of CO23- will promote the adsorption of sodium oleate on the surface of the mineral, thereby improve the recovery rates of the minerals. The addition of Fe3+ will promote the dissolution of magnesite and form a hydration layer on the surface of the particles, hinder the adsorption of collectors on the surface of the particles, thereby reduce the recovery rates of minerals. © 2024 Central South University of Technology.

Abstract ：
In order to improve the flotation separation of magnesite from dolomite effectively, the organic regulator, phenoxyacetyl chloride (POC), was first introduced as a selective depressant of magnesite, with dodecylamine (DDA) as the collector. The results of single mineral flotation showed that POC could selectively inhibit magnesite but hardly affect dolomite. The results of reverse flotation of a synthetic mixture of magnesite and dolomite were basically consistent with those of single mineral flotation. With DDA as the collector and POC as the depressant, dolomite floated selectively against magnesite. Magnesite and dolomite could be efficiently separated at pH 8.00 with a reagent scheme of 0.50 mg/mL POC and 30.00 mg/L DDA. When the mixed ore for the synthetic mineral, grading 42.60 % MgO and 2.84 % CaO, a magnesite concentrate with 46.85 % MgO and 0.45 % CaO was achieved. Contact angle, Zeta potential, Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and DFT analyses showed that POC selectively adsorbed on the surface of magnesite, by chelating Mg on the surface of magnesite. The results from the contact angle tests indicated that POC selectively reduced the surface hydrophobicity of magnesite in the DDA system. Besides, Zeta-potential measurements and FTIR analyses revealed that the addition of POC prior to DDA had no significant impact on the adsorption of DDA onto dolomite; the addition of POC strongly prevented DDA from being adsorbed onto magnesite, resulting in a significant difference in the flotation performances of the two minerals. Furthermore, XPS analyses and DFT calculations confirmed that the adsorption of POC on the magnesite surface could be attributed to the interaction between the POC electron-rich groups and the Mg exposed to magnesite, POC could be used as a high-performance inhibitor for the magnesite flotation to realize the decalcificationic. Based on these experimental results, a possible model for the flotation separation process of magnesite has been proposed.

Abstract ：
In order to effectively eliminate the effect of fine carbonate minerals on quartz flotation, the influence of fine siderite on quartz flotation was studied as well as the mechanism or role of ultrasonic treatment in the process. The results of adsorption capacity measurement and flotation solution chemical calculation show that fine siderite and its dissolved components have a great influence on the collector consumption and the surface properties of quartz. In addition, SEM, EDS and XPS analysis were used to study the surface morphology and chemical environment changes of quartz with and without ultrasonic treatment. The results of flotation test show that the recovery of quartz increase from 38.79% to 58.38% under the condition that ultrasonic time was 0.5 min and ultrasonic power was 200 W. The mechanical effect caused by ultrasonic cavitation can clean the quartz surface to a certain extent and increase its active sites, thus improving the floatability of quartz.

Abstract ：
In this study, tamarind polysaccharide gum was first used in the sulfidization flotation of azurite to improve the Cu grade of the concentrate via the depression of talc. The flotation and contact angle test results indicated that the hydrophobicity and floatability of talc were weakened, and the recovery decreased with the addition of tamarind polysaccharide gum, but the flotation behavior of azurite was barely influenced. At pH 8.0, using 30 mg/L tamarind polysaccharide gum with 200 mg/L Na2S and 400 mg/L NaBX to separate azurite and talc, the recoveries of which were 80.42% and 18.07%, respectively. To explore the adsorption mechanism of tamarind polysaccharide gum, zeta potential measurements, X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy analyses were conducted. The results indicated that tamarind polysaccharide gum selectively adsorbed on the talc surface, thus the flotation separation of azurite and talc was achieved, and the concentrate grade in the sulfidization flotation of azurite was increased.
