Exposure of the separator feed to intense vibration at the separator inlet eliminates the negative effects of adhesive interaction forces between finely divided particles on the process. The results include higher concentrate grades and improved recoveries.

These technologies may significantly reduce or completely eliminate the consumption of water currently used as a dispersion separation medium.

The studies were carried out at Mekhanobr-Tekhnika REC with the participation of employees of the Institute of Problems of Mechanical Engineering of RAS [1–5].
