Abstract (English): Anthracite, as a rare and valuable coal resource, holds substantial economic potential through deep desliming and quality enhancement. This study reveals that the introduction of sodium lignosulfonate during the ultrafine grinding process of anthracite facilitates the coupled regulation of interfacial properties within the ultrafine grinding-flotation system. Experimental results demonstrate that the addition of sodium lignosulfonate enhances grinding efficiency. Furthermore, flotation tests indicate that sodium lignosulfonate, when employed as a grinding aid, exerts a pronounced influence on flotation performance. An optimal dosage of 500 g/t sodium lignosulfonate significantly improves flotation deashing efficiency; however, excessive addition negatively affects the flotation process. Characterization analyses combined with EDLVO theoretical calculations further elucidate that sodium lignosulfonate enhances the hydrophilicity of coal particle surfaces, effectively suppresses spontaneous particle aggregation, and mitigates "mechanical entrainment" during flotation. This study proposes a novel technical approach, offering both theoretical insights and practical guidance for the industrial application of coupled interfacial regulation in the ultrafine grinding-flotation process of anthracite.

Abstract (Chinese): 无烟煤作为一种稀缺的煤炭资源, 通过深度降灰提质后能够创造较高的经济价值。通过试验 与理论多尺度结合的方式, 揭示无烟煤超细粉碎过程中引入木质素磺酸钠对无烟煤超细粉碎− 浮选体系界面性质的耦合调控机制。研磨试验结果显示, 在研磨过程中添加木质素磺酸钠可显著提 高研磨效率, 在相同磨矿条件下微细粒级产率显著提高。浮选试验进一步表明, 木质素磺酸钠作为 研磨助剂对浮选效果有显著影响, 即木质素磺酸钠用量为 500 g / t 时能够显著提高浮选脱灰效率, 而 过量添加木质素硫磺酸钠则对浮选过程产生不利影响。介观表征和扩展的经典胶体稳定 (EDLVO) 理 论计算结果显示, 在研磨过程中引入木质素磺酸钠作为研磨助剂能够显著增强煤颗粒表面的亲水性, 并有效抑制煤颗粒的自发团聚, 减少浮选过程中的机械夹带。研究提出的新颖技术路径, 为无烟煤 超细粉碎−浮选工艺耦合界面调控的工业化应用提供了理论依据与实践指导。 [ABSTRACT FROM AUTHOR]
