Iron ore is generally transported using a traditional method that releases significant amounts of dust into the environment. In contrast, the pipeline transportation of slurry is noticeably a sustainable approach for efficiently transporting iron ore by reducing the environmental pollution. The interparticle interaction of the iron ore particles should be mutually repulsive for steady dispersion. Surfactants and polymers adsorb efficiently at the solid/liquid interface due to their amphiphilic character, rendering the surface hydrophilic or hydrophobic to create a stable dispersion. The present review discusses the interaction of surfactants on the stabilization of solid particles for the ease of pipeline transportation using various types of stabilization mechanisms. In addition to the effect of surfactant alone, its combination with some other parameters such as particle size distribution, temperature, solid concentration, etc. has been discussed. The review also describes the detailed classification of iron ore, surfactant, and characteristic properties of surfactants.
铁矿石通常采用传统方法运输，这种方法会向环境中释放大量粉尘。相比之下，通过管道输送矿浆显然是一种可持续的方法，它通过减少环境污染来高效运输铁矿石。铁矿石颗粒间的相互作用应为相互排斥，以实现稳定分散。表面活性剂和聚合物因其两亲性而能有效吸附在固液界面，使表面具有亲水性或疏水性，从而形成稳定分散体。本综述利用各种稳定机制，讨论了表面活性剂对固体颗粒稳定化的作用，以便于管道运输。除了单独表面活性剂的作用外，还讨论了其与其他一些参数（如粒度分布、温度、固体浓度等）的组合。该综述还描述了铁矿石的详细分类、表面活性剂以及表面活性剂的特性。
