“…Recently, it was found that microwave pre-treatment of iron ore reduces the slurry viscosity and yield stress exhibiting shearthinning or pseudo-plastic behavior. The viscosity and density of microwave treated ore is always lower than that of untreated [31,37,52].…”

In this paper, the rheological parameters, characterisation, and the rheological behaviour of mineral ore slurry are reviewed and discussed in detail. Rheology is a study of flow phenomenon of matter, parameters like viscosity and the relationship between stress, strain, and time for the matter are helpful in defining rheology, these parameters have helped in classification of fluids into two broad categories - Newtonian and Non-Newtonian fluids. The rheological characteristics have a great impact in design and operation of the pipelines. This paper has a special emphasis on the iron ore slurry and its rheological behaviors which are highly affected by several physical and chemical properties (particle shape, particle size distribution, shear rate, pH value, solid concentration, viscosity, and slurry temperature) which also have been explained in particulars. The importance of rheology in slurry transportation makes it really important to define ways for controlling rheology that have proven to be helpful in stabilizing the slurry thus making the operation more efficient. Rheology is a major factor that affects the process of pipeline transportation of slurry which makes it such an important topic of study and research.

“…The iron and steel industries have grown exponentially worldwide due to huge amount of constructional activities. To meet the demand of iron ore, it is normally transported by rail and by road (truck and lorry) which causes serious environmental pollutions for particulate matters [1,2]. Transporting the iron ore by rail is cost effective as compared to road transportation.…”

“…Moreover, the rate of accident is more due to road transportation through trucks and lorries as such vehicles run in township crowed areas. To overcome such congested transportation networks and adopting an economic and environmentally friendly transportation system, the iron ore is now transported through pipelines in form of slurries and some more industries have ambitious future plans for installing such iron ore slurry pipelines [1,3].…”

The pipeline transportation of iron ore slurry (IOS) is an eco-friendly alternate mode to transport the raw materials to longer distance and reduce the transportation network congestion problems. Proper selection of surfactant could modify mineral’s viscosity, dispersion and wetting characteristics effectively as may be desired, which may further be monitored. A surfactant alters surface characteristics after being adsorbed onto minerals by altering the interfacial behaviour. This work is first report of the influence of a biosurfactant sourced from Aloe barbadensis Miller on the rheological behaviour of a high-grade iron ore (IO) sample at 45–72% by mass slurry concentrations range. The observed rheological parameters confirmed the non-Newtonian flow behaviour of the slurry. The collected IO and dried IOS samples were subjected to UV-Vis, XRF, PSD, XRD, SEM and EDS analyses. Experimental rheological data at varying concentrations was tested on various models to ascertain the best-fit rheological model for IOS transport. The Bingham model was found to be the most suitable to model the rheology of IOS. Experimental rheological behaviour of IOS was found to be linear with the yield stress. The study shall help to ascertain the suitability of a biosurfactant to stabilise high grade iron ores for pipeline transportation.

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.
