Rocks are crushed, sorted and washed, and then undergo beneficiation before transportation. The transportation of bauxite as dry or wet slurry changes the weight of ore and thereby both the cost of transportation and the carbon footprint (e.g. Rajkovic et al. 2016), as well as the potential for liquefaction risk during transport .

Upon extraction and transportation of bauxite to refineries, it undergoes the Bayer Process. In this process, crushed bauxite is combined with a sodium hydroxide solution to produce alumina. Subsequently, the alumina is subjected to the Hall-Heroult Process, wherein it is dissolved in molten cryolite and electrolyzed to obtain pure aluminum.

The surge in bauxite volumes from Guinea at the beginning of the year has been a key driver of this trend, with panamaxes increasingly diverting coal cargoes to cater to the rising demand for bauxite. As a result, bauxite has now become the second largest commodity carried by capesize vessels, trailing only behind iron ore, as reported by Arrow.

The primary focus of the present study is to demonstrate the role of particle concentration and size distribution on bauxite slurry rheology and slurry transportation. It was previously established that in such systems at shear rates in the range of 10–500 s−1, the slurry is free from wall slip and Taylor vortices. Hence, all our experiments were carried out in this …
