Abstract (en)
The procedure, designed to concentrate and separate fine particles (9, 10) of various solid substances of different densities, including minerals, consists of creating a pulp which is subjected to centrifuging and centripetal pulses. The centripetal pulses are created by injecting a fluid into the pulp in a direction that provides a component that is tangential to the centrifuging direction. The pulp is introduced into the centrifuging chamber (11) tangentially to its outer wall (2), and the denser fraction is withdrawn tangentiall to the same wall.
