It indicates that the iron ore slurry is very aggressive regardless to the travelled distance. Analyzing the results for the iron ore slurry concentrated at 1.6 m/s, for the first covered distance, 46 km (achieved after 8 h pumping), the time necessary for the thickness to be reduced by 5 mm is less than 5 years.
