摘要:
这是一篇矿物加工工程领域的文章。为促进磁化处理在铁矿浮选中的应用，为磁化处理理论体系的构建提供一定依据，研究了磁化处理水对赤铁矿和石英纯矿物浮选的影响，并从润湿性和吸附量方面进行了机理分析，进行了动力学验证实验。磁化场强150 mT，磁化时间6 min，1号磁场位型时，赤铁矿回收率为82.85%，提高了28.20%。磁化处理水有利于油酸钠在赤铁矿表面的吸附作用，降低了赤铁矿表面的润湿性，对石英无影响。磁化处理浮选用水后，赤铁矿浮选速率常数由0.54提高至0.61，较大回收率由57.18%提高至85.63%。表明磁化处理后赤铁矿浮选效果优于未磁化时，磁化处理可以提高赤铁矿浮选速率和回收率。条件实验、机理分析及动力学验证实验结果一致。
Abstract:This is an article in the field of mineral processing engineering. In order to promote the application of magnetization treatment in iron ore flotation and provide a certain basis for the construction of magnetization treatment theoretical system, the influence of magnetization treatment water on the flotation of pure minerals of hematite and quartz was studied, and the mechanism was analyzed from the aspects of wettability and adsorption capacity, and dynamic verification experiments were conducted. With a magnetization field strength of 150 mT and a magnetization time of 6 minutes, the recovery rate of hematite was 82.85%, an increase of 28.20%, at the position of the 1st magnetic field. Magnetization treatment of water is beneficial for the adsorption of sodium oleate on the surface of hematite, reducing its wettability and having no effect on quartz. After magnetization treatment of flotation water, the flotation rate constant of hematite increased from 0.54 to 0.61, and the maximum recovery rate increased from 57.18% to 85.63%. It indicates that the flotation effect of hematite after magnetization treatment is better than that without magnetization, and magnetization treatment can improve the flotation rate and recovery rate of hematite. The results of the condition test, mechanism analysis, and dynamic verification test are consistent.
