This CSV dataset (numbered 1–10) was used to accomplish rheological and flow characterization of iron ore slurries. CSV files 1–3 were used to create the plots in Fig. 2, Fig. 3 and Fig. 4, which are related to results of shear stress x shear rate, apparent viscosity x shear rate and Taylor number x shear rate, respectively (obtained by rotational rheometry). CSV files 4–6 were used to create the graphics depicted in Fig. 5, Fig. 6 and Fig. 7. They refer to experimental results of pressure gradient x mean flow velocity of iron ore slurries tested in a pumping loop tubular device (PLTD) plus friction factor x Reynolds number and friction factor x entropy parameter, respectively. Files 7 and 8 correpond to the data used to plot the rheograms (shear stress x shear rate and appparent viscosity x shear rate) obtained by tubular rheometry as shown in Fig. 8 and Fig. 9, respectively. Finally, the data presented in file 9 (shear stress x shear rate) and file 10 (apparent viscosity x shear rate) were used to plot the rheograms obtained by rotational and tubular devices, depicted in Fig. 10, Fig. 11, Fig. 12 and Fig. 13.
