Abstract
A process for reducing segregation of mining tailings while being deposited below the surface of a column of fluid is provided which comprises introducing the mining tailings into a downpipe having an inlet at or near the surface of the column of fluid and an outlet submerged in the column of fluid; providing at least one pressure drop element in the downpipe to prevent acceleration of the mining tailings and maintain the tailings flow therethrough; and providing a diffusing device at the outlet of the downpipe to reduce the velocity of the mining tailings as the tailings are discharged therefrom.
