Mining is a relevant economic activity in many countries. In the treatment of ores, water is an indispensable input. For classification of minerals, the mineral industry uses the hydrocyclone process, where water is used as the medium for transporting dispersed ore particles, that are separated from the liquid by centrifugal force inside anequipmentnamed hydrocyclone.The constant advance of
