Abstract

ABSTRACT. The transportation of minerals/ores in form of slurry through pipelines is an alternative, effective and also eco-friendly mode of transportation. Surfactants extracted from the plant sources are gaining high interest for the formulation and stabilization of high concentrated solid-water slurries. In this work, the role of a novel bio-surfactant extracted from Colocasia esculenta (L.) Schott on the stabilisation of iron ore slurry (IOS) was studied and reported first time. The collected iron ore powder (IOP) and dried IOS samples were analysed with the help of XRF, XRD, SEM and EDS analysis. The results confirmed that the surfactant molecules (present in aqueous Colocasia esculenta (L.) Schott) coated well on iron surface and forms an effective barrier between the iron ore (IO) particles. The studied rheological parameters for the slurry indicated non-Newtonian flow behaviour.

土芋草生物表面活性剂的作用分析肖特对高浓度铁矿浆输送稳定性的研究

摘要以矿浆形式通过管道运输矿物/矿石是一种替代的、有效的、环保的运输方式。从植物中提取的表面活性剂在高浓度固水浆料的配制和稳定方面受到了广泛的关注。在本研究中，从土芋中提取的一种新型生物表面活性剂的作用。本文首次对铁矿矿浆的稳定性进行了研究和报道。采用XRF、XRD、SEM、EDS等分析方法对采集的IOP和干燥后的IOP样品进行分析。结果证实，表面活性剂分子(L.)存在于水相中。在铁表面很好地涂覆，并在铁矿石(IO)颗粒之间形成有效的屏障。研究的浆料流变参数显示出非牛顿流动特性。关键词:铁矿矿浆;土芋;Schott, XRD, SEM，流变学测量公牛。化学。Soc。中国生物医学工程学报，2016,37(6)，1459-1470。DOI: https://dx.doi.org/10.4314/bcse.v37i6.13
