A diamond recovery process wherein a layer of grease is applied to a drum which is rotated about a horizontal axis, and wet particulate diamondiferous ore is fed to an upper surface of the rotating drum so that gangue falls to one side of the drum and diamonds, embedded in the grease, are carried to an opposing side of the drum at which the diamonds are recovered. L'invention concerne un procédé d'extraction de diamant dans lequel une couche de graisse est appliquée à un tambour qui est mis en rotation autour d'un axe horizontal, et un minerai diamantifère à particules humides est alimenté au niveau de la surface supérieure du tambour rotatif de sorte que la gangue tombe d'un côté du tambour et les diamants encastrés dans la graisse soient transportés sur le côté opposé du tambour, où les diamants sont extraits.
